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.

Thanks, it does. Can you try one thing for me? If you run the test on
sdc, try doing:

# echo 64 > /sys/block/sdc/queue/iosched/quantum

and repeat the test.

OK, that's done.

With the change of quantum, the throughput scores are now a little bit
