Hi,
I ran a few more benchmarks on 2.4.0 final with 3.6.24. The results were a little susprising (all on the same box, just after boot, no X):
MB/s user system cpu time 3.6.24 7.1 54.0 177,6 25% 14:57.5 3.6.24 14.5 53.2 152.4 47% 7:15.7 3.6.24 5.6 55.6 191.0 22% 18:36.4
reiserfs can do well, but notice how the system cpu seconds varies... I am not seeing such wild differences in ext2 runs, impling that they are due to something in reiserfs?
