I just finished a test on a current SuSE 9.0 with the following results:

single disk:
              1 write   1 read   2 write   2 read
ext2            20.26    25.46     18.90    12.72
ext3, journ.    19.96    25.04     19.83     7.96
reiserfs        20.03    25.33     19.08    12.47
xfs             20.00    25.31     19.10    12.50
jfs             18.85    25.49      7.89    25.37

So ext2, reiserfs and xfs seem to be fine. I personally stay away from
reiserfs because I have lost data after crashes several times. xfs seems
to be the best alternative, except for the long time it takes large
files during which vdr is blocked.
