Running benchmark tests (FFSB) on an ext4 filesystem, I noticed a
performance degradation (about 15-20 percent) in sequential write tests
between 2.6.19-rc6 and 2.6.21-rc4 kernels.
I ran the same tests on ext3 and XFS filesystems and I saw the same
performance difference between the two kernel versions for these two
filesystems.
I have also reproduced it between 2.6.20.7 and 2.6.21-rc7.
The FFSB tests run 16 threads, each creating 1GB files. The tests were
done on the same x86_64 system, with the same kernel configuration and
on the same scsi device. Below are the throughput values given by FFSB.
kernel XFS ext3
----------
2.6.20.7 48 MB/sec 44 MB/sec
2.6.21-rc7 38 MB/sec 37 MB/sec
Did anyone else run across the problem?
Is there a known issue?

That's a new discovery, thanks.
It could be due to I/O scheduler changes. Which one are you using? CFQ?
Or it could be that there has been some changed behaviour at the VFS/pagecache
layer: the VFS might be submitting little hunks of lots of files, rather than
large hunks of few files.
Or it could be a block-layer thing: perhaps some driver change has caused
us to be placing less data into the queue. Which device driver is that machine
using?
Being a simple soul, the first thing I'll try when I get near a test box
will be
for i in $(seq 1 16)
do
time dd if=/dev/zero of=$i bs=1M count=1024 &
done

Please tell me how you are running ffsb, and also please include a
dmessg from a booted system.

I tried first the test with dd, the results are similar to those of FFSB
tests, about 15 percent of degradation between 2.6.20.7 and 2.6.21-rc7.
I'm using the CFQ I/O scheduler. I changed it to the "deadline" one and
I don't have any more the problem, I've got similar throughput values
with 2.6.20.7 and 2.6.21-rc7 kernels.
So can we conclude that it's due to the CFQ scheduler?
I also checked the device driver used, the revision number is the same
in 2.6.20 and 2.6.21.

Hi,
our mails crossed! please see my response to Andrew.
You could reproduce the problem with dd command as suggested, it's more
easy.
I'm sending you the dmesg info. For my tests I used the scsci sdc device.
Hope this help,
Valérie
