Following are some numbers for ext2 & xfs
on my 2P 64MB box. I still have problems running
with 48 clients (vn_revalidate bug), so can't
produce consistent numbers yet for 48 clients.
This is fairly good results since XFS does well
on medium->high workloads. Experiments consisted
of 5 runs at each client number; since both
ext2 & xfs show variations, I took the best 3
out of the 5 runs.
