Unmapped folios accessed through file descriptors can be
underprotected. Those folios are added to the oldest generation based
on:
1. The fact that they are less costly to reclaim (no need to walk the
rmap and flush the TLB) and have less impact on performance (don't
cause major PFs and can be non-blocking if needed again).
2. The observation that they are likely to be single-use. E.g., for
client use cases like Android, its apps parse configuration files
and store the data in heap (anon); for server use cases like MySQL,
it reads from InnoDB files and holds the cached data for tables in
buffer pools (anon).
However, the oldest generation can be very short lived, and if so, it
doesn't provide the PID controller with enough time to respond to a
surge of refaults. (Note that the PID controller uses weighted
refaults and those from evicted generations only take a half of the
whole weight.) In other words, for a short lived generation, the
moving average smooths out the spike quickly.
To fix the problem:
1. For folios that are already on LRU, if they can be beyond the
tracking range of tiers, i.e., five accesses through file
descriptors, move them to the second oldest generation to give them
more time to age. (Note that tiers are used by the PID controller
to statistically determine whether folios accessed multiple times
through file descriptors are worth protecting.)
2. When adding unmapped folios to LRU, adjust the placement of them so
that they are not too close to the tail. The effect of this is
similar to the above.

The initial MGLRU patchset didn't include the memcg LRU support, and
it relied on should_abort_scan(), added by commit f76c83378851 ("mm:
multi-gen LRU: optimize multiple memcgs"), to "backoff to avoid
overshooting their aggregate reclaim target by too much".
Later on when the memcg LRU was added, should_abort_scan() was deemed
unnecessary, and the test results [1] showed no side effects after it
was removed by commit a579086c99ed ("mm: multi-gen LRU: remove
eviction fairness safeguard").
However, that test used memory.reclaim, which sets nr_to_reclaim to
SWAP_CLUSTER_MAX. So it can overshoot only by SWAP_CLUSTER_MAX-1
pages, i.e., from nr_reclaimed=nr_to_reclaim-1 to
nr_reclaimed=nr_to_reclaim+SWAP_CLUSTER_MAX-1. Compared with the batch
size kswapd sets to nr_to_reclaim, SWAP_CLUSTER_MAX is tiny. Therefore
that test isn't able to reproduce the worst case scenario, i.e.,
kswapd overshooting GBs on large systems and "consuming 100% CPU" (see
the Closes tag).
Bring back a simplified version of should_abort_scan() on top of the
memcg LRU, so that kswapd stops when all eligible zones are above
their respective high watermarks plus a small delta to lower the
chance of KSWAPD_HIGH_WMARK_HIT_QUICKLY. Note that this only applies
to order-0 reclaim, meaning compaction-induced reclaim can still run
wild (which is a different problem).

While investigating kswapd "consuming 100% CPU" [1] (also see
"mm/mglru: try to stop at high watermarks"), it was discovered that
the memcg LRU can breach the thrashing protection imposed by
min_ttl_ms.
Before the memcg LRU:
kswapd()
shrink_node_memcgs()
mem_cgroup_iter()
inc_max_seq() // always hit a different memcg
lru_gen_age_node()
mem_cgroup_iter()
check the timestamp of the oldest generation
After the memcg LRU:
kswapd()
shrink_many()
restart:
iterate the memcg LRU:
inc_max_seq() // occasionally hit the same memcg
if raced with lru_gen_rotate_memcg():
goto restart
lru_gen_age_node()
mem_cgroup_iter()
check the timestamp of the oldest generation
Specifically, when the restart happens in shrink_many(), it needs to
stick with the (memcg LRU) generation it began with. In other words,
it should neither re-read memcg_lru->seq nor age an lruvec of a
different generation. Otherwise it can hit the same memcg multiple
times without giving lru_gen_age_node() a chance to check the
timestamp of that memcg's oldest generation (against min_ttl_ms).

In the effort to reduce zombie memcgs [1], it was discovered that the
memcg LRU doesn't apply enough pressure on offlined memcgs.
Specifically, instead of rotating them to the tail of the current
generation (MEMCG_LRU_TAIL) for a second attempt, it moves them to the
next generation (MEMCG_LRU_YOUNG) after the first attempt.
Not applying enough pressure on offlined memcgs can cause them to
build up, and this can be particularly harmful to memory-constrained
systems.

Hi Yu,
Thanks you for your amazing works on MGLRU.
I believe this is the similar issue I was trying to resolve previously:
https://lwn.net/Articles/945266/
The idea is to use refault distance to decide if the page should be
place in oldest generation or some other gen, which per my test,
worked very well, and we have been using refault distance for MGLRU in
multiple workloads.
There are a few issues left in my previous RFC series, like anon pages
in MGLRU shouldn't be considered, I wanted to collect feedback or test
cases, but unfortunately it seems didn't get too much attention
upstream.
I think both this patch and my previous series are for solving the
file pages underpertected issue, and I did a quick test using this
series, for mongodb test, refault distance seems still a better
solution (I'm not saying these two optimization are mutually exclusive
though, just they do have some conflicts in implementation and solving
similar problem):
Previous result:

This patch:
==================================================================
Execution Results after 900 seconds

Executed Time (µs) Rate
STOCK_LEVEL 1594 27061522574.4 0.06 txn/s
------------------------------------------------------------------
TOTAL 1594 27061522574.4 0.06 txn/s
Unpatched version is always around ~500.
I think there are a few points here:
- Refault distance make use of page shadow so it can better
distinguish evicted pages of different access pattern (re-access
distance).
- Throttled refault distance can help hold part of workingset when
memory is too small to hold the whole workingset.
So maybe part of this patch and the bits of previous series can be
combined to work better on this issue, how do you think?

For example. maybe still keep the pages on oldest gen by default, but
if the page have a eligible shadow, then put it on min_seq + 1?

Also this can combine with refault distance check for setting the

This comment does not align with 86c79f6b5426
("mm: vmscan: do not reclaim from kswapd if there is any eligible zone").
Any thing special here?

I don't see how they are not: they essentially say the same thing ("no
more than needed") but with different units: zones or pages. IOW,
don't reclaim from more zones or pages than needed.

I'll try to find some time this week to look at your RFC. It'd be a
lot easier for me if you could share
1. your latest tree, preferably based on the mainline, and
2. your VM image containing the above test.

Sure, I'll update the RFC and try to provide an easier test reproducer.

Hi Yu,
I'm working on V4 of the RFC now, which just update some comments, and
skip anon page re-activation in refault path for mglru which was not
very helpful, only some tiny adjustment.
And I found it easier to test with fio, using following test script:
#!/bin/bash
swapoff -a
modprobe brd rd_nr=1 rd_size=16777216
mkfs.ext4 /dev/ram0
mount /dev/ram0 /mnt
mkdir -p /sys/fs/cgroup/benchmark
cd /sys/fs/cgroup/benchmark
echo 4G > memory.max
echo $$ > cgroup.procs
echo 3 > /proc/sys/vm/drop_caches
fio -name=mglru --numjobs=12 --directory=/mnt --size=1024m \
--buffered=1 --ioengine=io_uring --iodepth=128 \
--iodepth_batch_submit=32 --iodepth_batch_complete=32 \
--rw=randread --random_distribution=zipf:0.5 --norandommap \
--time_based --ramp_time=5m --runtime=5m --group_reporting
zipf:0.5 is used here to simulate a cached read with slight bias
towards certain pages.

fio uses ramdisk so LRU accuracy will have smaller impact. The Mongodb
test I provided before uses a SATA SSD so it will have a much higher
impact. I'll provides a script to setup the test case and run it, it's
more complex to setup than fio since involving setting up multiple
replicas and auth and hundreds of GB of test fixtures, I'm currently
occupied by some other tasks but will try best to send them out as
soon as possible.

Thanks! Apparently your RFC did show better IOPS with both access
patterns, which was a surprise to me because it had higher refaults
and usually higher refautls result in worse performance.
So I'm still trying to figure out why it turned out the opposite. My
current guess is that:
1. It had a very small but stable inactive LRU list, which was able to
fit into the L3 cache entirely.
2. It counted few folios as workingset and therefore incurred less
overhead from CONFIG_PSI and/or CONFIG_TASK_DELAY_ACCT.
Did you save workingset_refault_file when you ran the test? If so, can
you check the difference between this series and your RFC?

It seems I was right about #1 above. After I scaled your test up by 20x,
I saw my series performed ~5% faster with zipf and ~9% faster with random
accesses.
IOW, I made rd_size from 16GB to 320GB, memory.max from 4GB to 80GB,
--numjobs from 12 to 60 and --size from 1GB to 4GB.

Hi Yu,
Thank you so much for testing and sharing this result.
I'm not sure about #1, the ramdisk size, access data, are far larger
than L3 (16M on my CPU) even in down scaled test, and both random/zipf
shows similar result.

I think the problem might be related to this series ages faster and so
have higher overhead in some case. In your test the test is large
scaled so MGLRU just keep reclaiming last gen, no aging, and my RFC
bring extra overhead due to workingset checking and memcg flushing
(the memcg flushing patch in unstable tree may help?), and also the
current refault distance checking model, simply glued to MGLRU (some
known issues, the most obvious issue is that refault distance check
can't prevent the file page underprotected issue at all when active is
low or empty, and using active/inactive is not accurate enough for
MGLRU), not performing good enough.
And for the MongoDB test, I still didn't have enough time to tidy up
the setup scripts and modified repo yet, sorry about this, in past few
days I only have time to check this issue at late night... but a quick
test shows interesting reading too:

And I've turned off all unrelated features off (psi, delayacct) for
above tests. When PSI is on, the MongoDB test shows 70 - 100 PSI SOME,
it's not using a very high performance disk.
I think this could suggest some time evict of file page is not that
costly. And page shadow can store fine grained data of page's access
distance, so maybe I can tune the refault distance checking model for
MGLRU, combine with this series, which may help to improve the protect
policy to be more balanced (not too fast, and still accurate)?

It's the LRU list not pages. IOW, the kernel data structure, not the
content in LRU pages. Does it make sense?

Would you be able to try a larger configuration like above instead?

And thanks for providing the refaults I requested for -- your data
below confirms what I mentioned above:
For fio:
Your RFC This series Change
workingset_refault_file 628192729 596790506 -5%
IOPS 1862k 1830k -2%
For MongoDB:
Your RFC This series Change
workingset_refault_anon 10512 35277 +30%
workingset_refault_file 22751782 20335355 -11%
total 22762294 20370632 -11%
TPS 0.09 0.06 -33%
For MongoDB, this series should be a big win (but apparently it's not),
especially when using zram, since an anon refault should be a lot
cheaper than a file refault.
So, I'm baffled...
One important detail I forgot to mention: based on your data from
lru_gen_full, I think there is another difference between our Kconfigs:
Your Kconfig My Kconfig Max possible
LRU_REFS_WIDTH 1 2 2
This means you can only track 3 accesses through file descriptors
at most, and when you hit 3, the folio is moved to the next generation
by sort_folio() in the eviction path. IOW, your aging runs faster than
mine sine more folios are moved to the next generation (mine only does

Hi Yu,
Thanks for the info, my fault, I forgot to update my config as I was
testing some other features.
Buf after I changed LRU_REFS_WIDTH to 2 by disabling IDLE_PAGE, thing
got much worse for MongoDB test:
With LRU_REFS_WIDTH == 2:

Using same mongodb config (a 3 replica cluster using the same config):
{
"net": {
"bindIpAll": true,
"ipv6": false,
"maxIncomingConnections": 10000,
},
"setParameter": {
"disabledSecureAllocatorDomains": "*"
},
"replication": {
"oplogSizeMB": 10480,
"replSetName": "issa-tpcc_0"
},
"security": {
"keyFile": "/data/db/keyfile"
},
"storage": {
"dbPath": "/data/db/",
"syncPeriodSecs": 60,
"directoryPerDB": true,
"wiredTiger": {
"engineConfig": {
"cacheSizeGB": 5
}
}
},
"systemLog": {
"destination": "file",
"logAppend": true,
"logRotate": "rename",
"path": "/data/db/mongod.log",
"verbosity": 0
}
}
The test environment have 32g memory and 16 core.
Per my analyze, the access pattern for the mongodb test is that page
will be re-access long after it's evicted so PID controller won't
protect higher tier. That RFC will make use of the long existing
shadow to do feedback to PID/Gen so the result will be much better.
Still need more adjusting though, will try to do a rebase on top of
mm-unstable which includes your patch.
I've no idea why the workingset_refault_* is higher in the better
case, this a clearly an IO bound workload, Memory and IO is busy while
CPU is not full...

I ended up using docker.io/mongodb/mongodb-community-server:latest,
and it's not working:
# docker exec -it mongo-r1 mongosh --eval \
'"rs.initiate({
_id: "issa-tpcc_0",
members: [
{_id: 0, host: "mongo-r1"},
{_id: 1, host: "mongo-r2"},
{_id: 2, host: "mongo-r3"}
]
})"'
Emulate Docker CLI using podman. Create /etc/containers/nodocker to quiet msg.
Error: can only create exec sessions on running containers: container
state improper

Hi Yu,
I've updated the test repo:
https://github.com/ryncsn/emm-test-project/tree/master/mongo-cluster
I've tested it on top of latest Fedora Cloud Image 39 and it worked
well for me, the README now contains detailed and not hard to follow
steps to reproduce this test.
Also I've updated the patch series, I plan to sent out maybe RFC v4
later but need a another or couple days to tidy up and collect test
result:
https://github.com/ryncsn/linux/commits/kasong/devel/refault-distance-v4/
You may want to do test on top of it, I'll be very grateful if there
are any feedback.
It's on top of current mm-unstable to make it work well with your fix
too. I managed to tweak it to be compatible with this series, but it
seems it might cause over-protection of pages and so the performance
is slightly worse than RFC v3.
And this commit message contains my latest test result on the MongoDB case:
https://github.com/ryncsn/linux/commit/cd84e5c8e2449d33d411bce1d863bc391f36d7c8
And you can see it's a IO bound task (100% ioutil and low CPU usage)
and anon pages are really idle, using ZRAM/Same disk as swap result in
similar performance on patched kernel.
And about the aging overhead issue I suspected before (regression in
FIO due to more aging), I think it's true, and I added two patches:
https://github.com/ryncsn/linux/commit/f80cc280752da59272870378947aad6c822be2b4
https://github.com/ryncsn/linux/commit/01d091c98077a74bc70153cc7a0179a17da4f26f
In the test cases we talked about above, where > ~100 generations are
generated during FIO test, I suspected that the aging overhead is
large and causing performance drain.
After these two patches, for a similar test cases, FIO improved from this:
Run status group 0 (all jobs):
READ: bw=7593MiB/s (7962MB/s), 7593MiB/s-7593MiB/s
(7962MB/s-7962MB/s), io=2225GiB (2389GB), run=300002-300002msec
workingset_refault_anon 0
workingset_refault_file 641594126
To this:
Run status group 0 (all jobs):
READ: bw=7747MiB/s (8124MB/s), 7747MiB/s-7747MiB/s
(8124MB/s-8124MB/s), io=2270GiB (2437GB), run=300001-300001msec
workingset_refault_anon 0
workingset_refault_file 641511205
lru_gen stat is similar for both case:

The overhead of cmpxchg on page flag update is unavoidable though. I
think I could send out the two bulk update patch first for a proper
review first?

I think you just broke it by
https://github.com/ryncsn/py-tpcc/commit/7b9b380d636cb84faa5b11b5562e531f924eeb7e
(But it's also possible you actually wanted me to use this latest
commit but forgot to account for it in your instructions.)

Ah, you are right, I attempted to convert it to Python3 but found it
only brought more trouble, so I gave up and the instruction is still
using Python2. However I accidentally pushed the WIP python3 convert
commit... I've reset the repo to
https://github.com/ryncsn/py-tpcc/commit/86e862c5cf3b2d1f51e0297742fa837c7a99ebf8,
this is working well. Sorry for the inconvenient.

Thanks -- I was able to reproduce results similar to yours.
It turned out the mystery (fewer refaults but worse performance) was caused by
13.89% 13.89% kswapd0 [kernel.vmlinux] [k]
__list_del_entry_valid_or_report
Apparently Fedora has CONFIG_DEBUG_LIST=y by default, and after I
turned it off (the only change I made), this series showed better TPS
(I used"--duration=10800" for more reliable results):
v6.7-rc6 RFC [1] change
total txns 25024 24672 +1%
workingset_refault_anon 573668 680248 -16%
workingset_refault_file 260631976 265808452 -2%
I think this is easy to explain: this series is "lazy", i.e.,
deferring the protection to eviction time, whereas your RFC tries to
do it upfront, i.e., at (re)fault time. The advantage of the former is
that it has more up-to-date information because a folio that is hot
when it's faulted in doesn't mean it's still hot later when memory
pressure kicks in. The disadvantage is that it needs to protect folios
that are still hot at eviction time, by moving them to a younger
generation, where the slow down happened with CONFIG_DEBUG_LIST=y.
(It's not really a priority for me to investigate why
__list_del_entry_valid_or_report() is so heavy. Hopefully someone else
can shed some light on it.)
[1] v3 on top of v6.7-rc6 with "mm/mglru: fix underprotected page
cache" reverted.

Hi Yu,
Thanks for the testing, and merry xmas.

I'm not sure about this, if the task is CPU bounded, this could
explain. But it's not, the performance gap is larger when tested on
slow IO device.
The iostat output during my test run:
avg-cpu: %user %nice %system %iowait %steal %idle
7.40 0.00 2.42 83.37 0.00 6.80
Device r/s w/s rkB/s wkB/s rrqm/s wrqm/s

vdb 5999.30 4.80 104433.60 84.00 0.00 8.30

0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00
You can see CPU is waiting for IO, %user is always around 10%.
The hotspot you posted only take up 13.89% of the runtime, which
shouldn't cause so much performance drop.

I have disabled CONFIG_DEBUG_LIST when doing performance comparison test.
I believe you are using higher performance SSD, so the bottle neck is
CPU, and the RFC involves more lru/memcg counter update/iteration, so
it is slower by 1%.

I've just setup another cluster with high performance SSD, where now
CPU is the bottle neck to better understand this. Will try to do more
test to see if I can find out something.

I ran the benchmark on the slowest bare metal I have that roughly
matches your CPU/DRAM configurations (ThinkPad P1 G4
https://support.lenovo.com/us/en/solutions/pd031426).
But it seems you used a VM (vda/vdb) -- I never run performance
benchmarks in VMs because the host and hypervisor can complicate
things, for example, in this case, is it possible the host page cache
cached your disk image containing the database files?

I'd suggest we both stick to bare metal until we can reconcile our
test results. Otherwise, there'd be too many moving parts for us to
get to the bottom of this.

Also I'd suggest we both use the same distro you shared with me and
the default .config except CONFIG_DEBUG_LIST=n, and v6.7-rc6 for now.
(I'm attaching the default .config based on /boot/config-6.5.6-300.fc39.x86_64.)

Hi Yu
I've been adapting and testing the refault distance series based on
latest 6.7. Also I found a serious bug in my previous V3, so I updated
it here with some importance changes (using a seperate refault
distance model, instead of glueing to active/inactive model):
https://github.com/ryncsn/linux/commits/kasong/devel/refault-distance-2024-1/
So far I can conclude that previous result is not caused by host
cache, I setup a baremetal test environment, strictly using your
config, I gathered some data (I also updated the refault distance
patch series, updated version in link above, and also the baremetal
hava a fast NVME so the performance gap wasn't so large but still
stably observable):
With latest 6.7 (Your config):

You see actually refault distance is now protecting more anon page,
total IO on ZRAM is lower, It's mostly CPU bound, and NVME is fast
enough, and result in a better performance.
Things get more interesting if I disable page idle flag (so refs bits
is extended, in your config, refs bit is only one bit, so it maybe
overprotect file pages):
Latest 6.7 (You config with page idle flag disabled):

And still refault distance series is better, and refault is also lower
for both anon/file pages.

I did some more test using MySQL and other workflow, no performance
drop observed so far.
And with a loop MongoDB test (keep running 900s test in loop) using my
previous VM env
(the SATA SSD vdb is using cache bypass so not a host cache issue here)
I found one thing interesting (refs bit is set to 2 in config):
Loop test using 6.7:

It seems the performance will drain as the test keep running (might be
caused by MongoDB anon usage rising or DB internal caching/logging),
that explains why for a long term test the performance gap seem to be
smaller. The VM have a poor IO performance so the test run speed is
much slower too, take a long time to warm up.
But I think it's clear that refault distance series will boost the
performance during warm up, and for long time workload it's also
looking better, especially for low IO performance machines.
I still can't explain about why workingset_refault is higher for the
better case in the VM environment... I can resetup/reboot/randomize
the test the the performance is same here. My guess is maybe related
to readahead or some kernel space IO path issue? The actual IO usage
is lower when refault distance series is applied.
I notices a slight performance regression (1 - 3%) for pure in-mem FIO
though, the "bulk series" I sent previous can help improve it.
There is a bug in my previous V3 that will cause PID controller to
lost control in long term (due to a bugged bit operation, my bad),
which I've fixed in link above, I can send out new series if you think
it's acceptable.

Hi Yu,
Thanks for the patch, it helped in some degrees, but not as effective:
On that exclusive baremetal, I did a resetup, rebase on 6.7 mainline
and reran the test:

The peak performance almost equal, but still starts slow, refault is
higher too. File refault might be interfered due to some IO layer
issue, but anon refault is always accurate.
I see the improvement you did in the attachment patch, I think
actually they are not in conflict with the refault distance series.
Maybe they can be combined into a even better result.
Refault distance (which originally used by active/inactive LRU) is
used here to give evicted pages priorities based on eviction distance
and add extra feedback to PID and gen. While the PID info recorded in
page flags/shadow represents pages's access pattern before eviction,
and all the check and logics about it can also be improved.
One critical effect of the refault distance series that boost the
MongoDB startup (and I haven't see any negative effect of it on other
test / workload / benchmark yet, except the overhead of memcg
statistics itself) is it prevents overprotecting of tier 0 page: that
is, a tier 0 page evicted but refaulted very quickly (refault distance
< LRU / MAX_NR_GEN, this value may worth some more adjustment, but
with LRU / MAX_NR_GEN, it can be imaged as an idea that having a small
shadow gen holding these page shadows...) will be categorised as tier
1 and get protect. Other wise, if I got everything right, when most
pages are stuck in tier 0 and keep refaulting, tier 0 will have a very
high refault rate, and no pages will be protect, until randomness
causes quick repeated read of some page, so they get promoted to tier
3 get get protected.
Now min_seq contains lower tier pages and new pages will be added to
min_seq too, so min_seq will stay for a long time, while min_seq + 1
holds protected full ref tier 3 pages and they stay long enough to get
promoted as tier 3 again, so they will always be kept in memory.
Now MongoDB will perform well even without refault distance series,
but this period may take a long time (~15 min for the MongoDB test for
SATA SSD, which is based on a real workload), long enough to cause
real issue.
And this also means PID won't react to workload change fast enough.
Also the anon refault's refs value is adjusted by refault distance too
in the series, it tries to split the whole LRU as at least two gens
for refaulted pages (only page with refault distance < LRU /
MIN_NR_GEN will have full refs set, else will have refs - 1 set as
penalty for long time evicted and unused page, which complies with
LRU's nature). Which seems actually decreased refault of anon pages.
There are some other issue that refault distance series is trying to
solve too, eg. if there is a user agent force MGLRU to age
periodically for proactive memory reclaim, or MGLRU simply ages fast,
min_seq will grow periodically and PID won't catch enough feedback
using previous logic.

Thanks. So far I've been making shots in the dark since I haven't been
able to reproduce your results on bare metal or VMs. So, either the
benchmark itself is not reliable, which according to your results is
unlikely, or I've been using different hardware configurations. Do you
think you can share some off-the-shelf hardware configuration that I
can buy and use to reliably reproduce your results? Ideally we use the
exactly same model from, for example, Dell, HP or Lenovo.
