Please tell me how you are running ffsb, and also please include a

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.
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
better in 2.6.21 than in 2.6.20.
Wonderful, now try the patch I sent in the next mail and repeat the
test.
That's done too.
Now I've got the same results in 2.6.21 as in 2.6.20.
Thanks,
Valérie
