The original posting of this disappeared into the ether so here is another copy
for lkml.

Here follow the contest (http://contest.kolivas.net) benchmark results up to and
including 2.5.41

2.5.41 [1]              91.1    73      38      30      1.36

Proportional change here. Time longer than .40 but load also achieving more in
that time; not a real performance penalty.

2.5.41 [2]              607.5   13      47      12      9.04

Something happened here. Under heavy writing load it started choking again.
Noticeably detrimental.

2.5.41 [1]              101.1   75      7       4       1.51

Basically very similar results except for write loads being allowed to do more
to the detriment of other tasks.

Below are also the experimental loads not included in the stable release of contest:

tarx_load:
Kernel [runs]           Time    CPU%    Loads   LCPU%   Ratio
2.4.19 [1]              132.4   55      2       9       1.97
2.5.38 [1]              120.5   63      2       8       1.79
2.5.39 [1]              108.3   69      1       6       1.61
2.5.40 [1]              110.7   68      1       6       1.65
2.5.40-mm2 [1]          188.1   39      3       7       2.80
2.5.41 [2]              138.8   53      2       8       2.07

Tar extract load seems to be doing proportionately more work than .40
