d'oh.... sorry, now actually forked.
Hello Minchan,
forked into a separate tread.

interesting. the retry jump should go higher, we have "user_mem = kmap_atomic(page)"
which we unmap right after compression, because a) we don't need
uncompressed memory anymore b) zs_malloc() can sleep and we can't have atomic
mapping around. the nasty thing here is is_partial_io(). we need to re-do
if (is_partial_io(bvec))
memcpy(uncmem + offset, user_mem + bvec-bv_offset,
bvec-bv_len);
once again in the worst case.
so zs_malloc((gfp &~ __GFP_DIRECT_RECLAIM | GFP_NOWARN) so far can cause
double memcpy() and double compression. just to outline this.
the test.
I executed a number of iozone tests, on each iteration re-creating zram
device (3GB, LZO, EXT4. the box has 4 x86_64 CPUs).
$DEVICE_SZ=3G
$FREE_SPACE is 10% of $DEVICE_SZ
time ./iozone -t $i -R -r $((8*$i))K -s $((($DEVICE_SZ/$i - $FREE_SPACE)/(1024*1024)))M -I +Z

so when the number of active tasks become larger than the number
of online CPUS, iozone reports a bit hard to understand data. I
can assume that since now we keep the preemption disabled longer
in write path, a concurrent operation (READ or WRITE) cannot preempt
current anymore... slightly suspicious.
the other hard to understand thing is why do READ-only tests have
such a huge jitter. READ-only tests don't depend on streams, they
don't even use them, we supply compressed data directly to
decompression api.
may be better retire iozone and never use it again.
"118 insertions(+), 238 deletions(-)" the patches remove a big

yes, was going to investigate in more details but got interrupted,
will return back to it today/tomorrow.

oh, sorry, sure! attached (because it's not a real patch submission
yet, but they look more or less ready I guess).
patches are against next-20160324.

>From 6bf369f2180dad1c8013a4847ec09d3b9056e910 Mon Sep 17 00:00:00 2001
From: Sergey Senozhatsky <sergey.senozhatsky@gmail.com>
Subject: [PATCH 1/2] zsmalloc: require GFP in zs_malloc()
Pass GFP flags to zs_malloc() instead of using fixed ones (set
during pool creation), so we can be more flexible. Apart from
that, this also align zs_malloc() interface with zspool/zbud.

In my test, read is stable. It seems iozone or fs made noise in your test.
Benefit cause by per-cpu on write side is about 10% which is not huge
compared to your previous post.
Hmm, Could you retest to who how the benefit is big?

Hello Minchan,
sorry for long reply.

I used a bit different script. no `buffer_compress_percentage' option,
because it provide "a mix of random data and zeroes"
buffer_compress_percentage=int
If this is set, then fio will attempt to provide IO buffer content
(on WRITEs) that compress to the specified level. Fio does this by
providing a mix of random data and zeroes
and I also used scramble_buffers=0. but default scramble_buffers is
true, so
scramble_buffers=bool
If refill_buffers is too costly and the target is using data
deduplication, then setting this option will slightly modify the IO
buffer contents to defeat normal de-dupe attempts. This is not
enough to defeat more clever block compression attempts, but it will
stop naive dedupe of blocks. Default: true.
hm, but I guess it's not enough; fio probably will have different
data (well, only if we didn't ask it to zero-fill the buffers) for
different tests, causing different zram->zsmalloc behaviour. need
to check it.

sure. the results are:
- seq-read
- rand-read
- seq-write
- rand-write (READ + WRITE)
- mixed-seq

Normally, zram's compression ratio is 3 or 2 so I used it.
Hmm, isn't it more real practice usecase?
If we don't use buffer_compress_percentage, what's the content in the buffer?

Your case is 40% win. It's huge, Nice!
I tested with your guide line(i.e., no buffer_compress_percentage,
scramble_buffers=0) but still 10% enhance in my machine.
Hmm,,,
How about if you test my fio job.file in your machine?
Still, it's 40% win?
Also, I want to test again in your exactly same configuration.
Could you tell me zram environment(ie, disksize, compression
algorithm) and share me your job.file of fio?
Thanks.

this option guarantees that the supplied to zram data will have
a requested compression ratio? hm, but we never do that in real
life, zram sees random data.

that's a good question. I quickly looked into the fio source code,
we need to use "buffer_pattern=str" option, I think. so the buffers
will be filled with the same data.
I don't mind to have buffer_compress_percentage as a separate test (set
as a local test option), but I think that using common buffer pattern
adds more confidence when we compare test results.

I agree it's hard to create such random read data with benchmark.
One option is that we share swap dump data of real product, for exmaple,
android or webOS and feed it to the benchmark. But as you know, it
cannot cover all of workload, either. So, to just easy test, I wanted
to make represntative compression ratio data and fio provides option
for it via buffer_compress_percentage.
It would be better rather than feeding random data which could make
lots of noise for each test cycle.

If we both uses same "buffer_compress_percentage=something", it's
good to compare. The benefit of buffer_compress_percentage is we can
change compression ratio easily in zram testing and see various
test to see what compression ratio or speed affects the system.

I tested with you suggested parameter.
In my side, win is better compared to my previous test but it seems
your test is so fast. IOW, filesize is small and loops is just 1.
Please test filesize=500m loops=10 or 20.
It can make your test more stable and enhance is 10~20% in my side.
Let's discuss further once test result between us is consistent.
Thanks.

let's start with "common data" (buffer_pattern=str), not common
compression ratio. buffer_compress_percentage=something is calculated
for which compression algorithm? deflate (zlib)? or it's something else?
we use lzo/lz4, common data is more predictable.

that will require 5G zram, I don't have that much ram on the box so I'll
test later today on another box.
I split the device size between jobs. if I have 10 jobs, then the file
size of each job is DISK_SIZE/10; but in total jobs write/read DEVICE_SZ
bytes. jobs start with large 1 * DEVICE_SZ/1 files and go down to
10 * DEVICE_SZ/10 files.

We are using rw_page so I/O scheduler is not related.
Anyway, I configured my machine as you said but still see 10~20% enhance. :(
Hmm, could you post your .config?
I want to investigate why such difference happens between our machines.
The reason I want to see such *big enhance* in my machine is that
as you know, with per-cpu, zram's write path will lose blockable section
so it would make upcoming features's implementation hard.
We also should test it in very low memory situation so every write path
retry it(i.e., dobule compression). With it, I want to see how many
performance can drop.
If both test(normal: huge win low memory: small regression) are fine,
we can go per-cpu approach at the cost of giving up blockable section.
:)
Thanks.

yes, agree. added it just in case.

I see. well, depending on what new features are about to come in, we
can utilize the same per-cpu mechanism if we are talking about some
sort of buffers, streams, etc.

one of the boxen I use has only 4G of memory, so "re-compressions" do
happen there. I can add a simple counter (just for testing purposes)
to see how often.

yep.

Hello Minchan,
sorry, it took me so long to return back to testing.
I collected extended stats (perf), just like you requested.
- 3G zram, lzo; 4 CPU x86_64 box.
- fio with perf stat
4 streams 8 streams per-cpu

the test don't include 're-compresion path'.

Great!
So, based on your experiment, the reason I couldn't see such huge win
in my mahcine is cache size difference(i.e., yours is twice than mine,
IIRC.) and my perf stat didn't show such big difference.
If I have a time, I will test it in bigger machine.

I'm convinced now with your data. Super thanks!
However, as you know, we need data how bad it is in heavy memory pressure.
Maybe, you can test it with fio and backgound memory hogger,
Thanks for the test, Sergey!

quite possible it's due to the cache size.

it's really hard to produce stable test results when the system
is under mem pressure.
first, I modified zram to export the re-compression number
(put cpu stream and re-try handler allocation)
mm_stat for numjobs{1..10}. the number of re-compressions is in "< NUM>" format
3221225472 3221225472 3221225472 0 3221229568 0 0 < 6421>

2899095552 2899095552 2899095552 0 2899136512 78643 0 < 7485>
as we can see, the number of re-compressions can vary from 6421 to 8699.
the test:
-- 4 GB x86_64 box
-- zram 3GB, lzo
-- mem-hogger pre-faults 3GB of pages before the fio test
-- fio test has been modified to have 11% compression ratio (to increase the
chances of re-compressions)
-- buffer_compress_percentage=11
-- scramble_buffers=0
considering buffer_compress_percentage=11, the box was under somewhat
heavy pressure.
now, the results
fio stats
4 streams 8 streams per cpu

It would be great when we see the below ratio for each test.
1-compression : 2(re)-compression

Could you test concurrent mem hogger with fio rather than pre-fault before fio test
in next submit?

Yeb, Even, recompression case is fater than old but want to see more heavy memory
pressure case and the ratio I mentioned above.
If the result is still good, please send public patch with number.
Thanks for looking this, Sergey!

this test will not prove anything, unfortunately. I performed it;
and it's impossible to guarantee even remotely stable results.
mem-hogger process can spend on pre-fault from 41 to 81 seconds;
so I'm quite sceptical about the actual value of this test.

I did quite heavy testing over the last 7 days, with numerous OOM kills
and OOM panics.

Okay, I think it's worth to merge enough and see the result.
Please send formal patch which has recompression stat. ;-)
Thanks.

correction: those 41-81s spikes in mem-hogger were observed under
different scenario: 10GB zram with 6GB mem-hogger on a 4GB system.
I'll do another round of tests (with parallel mem-hogger pre-fault
and 4GB/4GB zram/mem-hogger split) and collect the number that you
asked for.
thanks!

Hello,
more tests. I did only 8streams vs per-cpu this time. the changes
to the test are:
-- mem-hogger now per-faults pages in parallel with fio
-- mem-hogger alloc size increased from 3GB to 4GB.
the system couldn't survive 4GB/4GB zram(buffer_compress_percentage=11)/mem-hogger
split (OOM), so I executed the 3GB/4GB test (close to system's OOM edge).
-- 4 GB x86_64
-- 3 GB zram lzo
firts, the mm_stat. <num_writes / num_recompressions>

per-cpu in general looks better in this test (jobs4): less stalls, less
branches, less misses, better fio speeds (except for WRITE: 630690KB/s 495078KB/s).
the system was under pressure, so quite possible that it took more time to kill the
process, thus execution time is in favor of 8 streams test.
