I have been doing some dbench runs with the original and latest (Jan 4 22:xx)
prerelease.diff kernels. Looks like both the latest kernels and the reiserfs
patch both are costing some performance.
prerelease
MB/s user system cpu time
ext2 14.6 50.5s 76.4s 29% 7:14.9m
ext2 12.6 50.9s 76.7s 25% 8:23.6m
reiser 14.5 53.8s 149.2s 46% 7:16.1m
reiser 10.7 54.1s 154.5s 35% 9:49.9m
prerelease (2.4.0 jan 4 22:xx)
MB/s user system cpu time
ext2 10.5 52.8s 81.5s 22% 10:02.3m
reiser 5.8 54.6s 198.5s 23% 18:12.5m
reiser 6.4 55.1s 188.7s 24% 16.19.3m
Using the notail reiserfs mount option improves the reiserfs numbers 10-20%
with both kernels.
All benchmarks run on a K6-III 400 with 128M just after boot with no X
running.
