yes, that can make a difference.
OK. Anyway, the new machine is also running on ext4. The number of
fsyncs/second is a lot higher there (different controller and disks
though)
In the meantime, I've also set up a testing machine with the same type
of controller, but this time with 4 146GB SAS disks in RAID10.
Results are similar to the other 2 machines:
FSYNCS/SECOND: 219.32
I've also tried upgrading the controller firmware to the latest version
on this one, but no change.
Also on an ext3 filesystem, performance is similar:
FSYNCS/SECOND: 220.11
Hmm on yet another machine, same controller, same disks, but this time
RAID1, with ext3 on top of LVM:
FSYNCS/SECOND: 2308.78
This machine is running a standard debian squeeze however.
