Have you benchmarked these machines to determine the max write load
capacity on reiserfs? Are you using a vanilla kernel or one with
patches applied?
I've done a few of my own benchmarks of the data logging patches, but it
would be great to see some independent verification of the speedups in a
real mail server workload.
