Have you checked out the FAQ?

Also, the man page for mkfs.xfs is very usefull.
The only things that I have heard are:
a. On large volumes keep dcount lower than default.
mkfs.xfs -d agcount=x
* agcount has to align with sunit and swidth but I don't com
b. On RAID arrangements, if your RAID is hardware use:
mkfs.xfs -d suinit=<raid block size>k,swidth=<(n) disks>
* I also saw one post that said on RAID5 use
* swith=<(n-1) disks>
c. Increase the size of the log:
mkfs.xfs -l size=32m
* maybe someone of greater knowledge can comment on
* determining what size is reasonable.
d. Mount with more logbufs:
o logbufs=4 or logbufs=8, this increases (from 2) the number of
in memory log buffers. This means you can have more active
transactions at once, and can still perform metadata changes
while the log is being synced to disk. The flip side of this
is that the amount of metadata changes which may be lost on
crash is greater.
e. evaluate volume creation options with the '-N' switch. Take note of
the output to help decide if what's being done looks optimal.
