XFS Filesystem performance tweaking on Linux
Published January 14th, 2008 in Kernel-Panik.com, Linux, howto, xfsSome years ago I found this old but still usefull guide for xfs performance tweaking on linux:
Filesystem performance tweaking with XFS on Linux
which is, esencially, a two-steps simple procedure:
Create xfs filesystem with a 64 megabyte log
# mkfs.xfs -f -l size=64m /dev/hda3
Mount filesystem with 8 log buffers, and atime and diratime disabled
# mount -o noatime,nodiratime,logbufs=8 /dev/hda3 /mnt/gentoo/
These simple tweaks do help! specially on large RAID partitions.

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
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?
