I found that CFQ's performance is worse than other IO scheduer in some cases
I confirmed its phenomenon when I executed dump command and sysbench on 2.6.28.
In dump(version:dump-0.4b41-2.fc6), I confirmed
the speed under CFQ is slower than other IO schedulers.
The Test Result(dump):
UNIT:Mb/sec
_______________________
| IO | |
| scheduler | Speed |
+------------|--------|
|cfq | 24.310 |
|noop | 36.885 |
|anticipatory| 34.956 |
|deadline | 36.758 |
+----------------------
Steps to reproduce(dump):
#dump -0uf /dev/null /dev/sda6
#df -h /dev/sda6
Filesystem Size Used Avail Use% Mounted on
/dev/sda6 19G 10G 7.6G 57% /mnt
In sysbench(version:sysbench-0.4.10), I confirmed followings.
- CFQ's performance is worse than other IO schedulers when only multiple
threads test.
(There is no difference under single thread test.)
- It is worse than other IO scheduler when
I used read mode. (No regression in write mode).
- There is no difference among other IO schedulers. (e.g noop deadline)
The Test Result(sysbench):
UNIT:Mb/sec

(7)#sysbench --test=fileio --num-threads=5 --file-total-size=10G --file-test-mode=seqrd cleanup
when doing step 2 or 5, sysbench creats 128 files, and 80M each one.
when doing step 4 or 7, sysbench deletes the files.
when doing step 3 or 6, thread reads these files continuously and
reads file-block-size(default:16Kbyte) at once, just like :
t_0 t_0 t_0 t_0 t_0 t_0 t_0
^ ^ ^ ^ ^ ^ ^

I don't know that much about the IO workload that sysbench generates, so it's hard to say. Since you both use SATA, I'm assuming you have write caching enabled on that drive? What file system and mount options are you using? > Jens, multi threads interleave the same file, and there may be > some requests that can merge but not merged on different thread queue, > So the CFQ performs poorly, right? You can test that theory by editing block/cfq-iosched.c:cfq_allow_merge(), changing it to return 1 always. I'll try and rerun this test here on various bits of storage and see what it turns up! -- Jens Axboe ^ permalink raw reply [flat|nested] 12+ messages in thread

If it's a sata drive, then it'll have write caching enabled (unless it's some custom firmware for storage units).

I understood your description, my suggested edit would make sure that you always do merging. CFQ manages a cfq_queue per process OR thread, the request queue is the same.

The reason for this is that the dump command interleaves I/O between two (or three?) cooperating processes. This is about the worst case scenario you can get for CFQ, as the I/O access pattern within each process is sequential. Thus, CFQ will idle for a number of milliseconds waiting for the current process to issue more I/O before switching to the next. Now, this behaviour can be changed with tuning. However, if the dump command simply shared I/O contexts between cooperating processes, CFQ could make more intelligent decisions about I/O scheduling. So, here are the numbers, running under 2.6.28-rc3. deadline 82241 kB/s cfq 34143 kB/s cfq-shared 82241 kB/s cfq-shared denotes that the dump utility was patched with the attached patch to share I/O contexts. As you can see, with a very little bit of code change, we can drastically increase the performance of dump under CFQ (which is the default I/O scheduler used in a number of distributions). For more information on the underlying problems, you can refer to the following kernel discussion: http://lkml.org/lkml/2008/11/9/133 Comments are appreciated.
