Buy more disks. ;)
XFS is not really optimised for single disk, metadata intensive,
small file workloads. It scales by being able to keep lots of disks
busy at the same time. Those algorithms don't map to single disk
configs as efficiently as a filesystem that was specifically
designed for optimal performance for these workloads (like
reiserfs). We're working on making it better, but that takes time....
Cheers,
Dave.
