He was referring to the preceding answer (mudrii's one).

Thanks to all the hints!

Bock: I am using noatime and nodiratime - What do you mean by nobarrier?

the mount option nobarrier increases the risk of a filesystem failure after an unexpected shutdown. I don't recommend to use it

I tried a 128m log too, but didn't find any significant performance increase vs. a 64m log... I use raid 5 boxes though.

I haven't tested the difference with nobarrier activated, does it have a significative improvement?

Hi
I use xfs on my RAID 1 server
mkfs.xfs -l internal,size=128m -d agcount=8 /dev/md0
mount -t xfs /dev/md0 /mnt/gentoo -o noatime,nodiratime,nobarrier,logbufs=8
