Here are contest benchmarks using osdl hardware. More resolution has been 
added to the io loads and read load (thanks Aggelos)

seems the scheduler changes have changed the balance of what work is done with 
this process load. No cpu cycles are wasted so it is not necessarily a bad 
result.

ctar_load:

2.5.59          3       98      80.6    2.0     5.1     1.24

2.5.59-mm8      3       152     50.0    35.4    13.1    1.92

This seems to be creeping up to the same as 2.5.59

read_load:
Kernel     [runs]       Time    CPU%    Loads   LCPU%   Ratio
2.5.59          3       101     77.2    6.3     5.0     1.28
2.5.59-mm7      3       94      80.9    2.8     2.1     1.21
2.5.59-mm8      3       93      81.7    2.8     2.2     1.18

2.5.59-mm8      3       98      78.6    0.0     6.1     1.24
mem_load:

2.5.59-mm7      4       92      82.6    45.5    1.4     1.18
2.5.59-mm8      3       97      80.4    53.3    2.1     1.23
dbench_load:
Kernel     [runs]       Time    CPU%    Loads   LCPU%   Ratio
2.5.59          3       126     60.3    3.3     22.2    1.59
2.5.59-mm7      4       121     62.0    2.8     24.8    1.55
2.5.59-mm8      3       212     35.8    11.0    47.2    2.68

and this seems to be taking significantly longer

io_other:
Kernel     [runs]       Time    CPU%    Loads   LCPU%   Ratio
2.5.59          3       89      84.3    11.2    5.4     1.13
2.5.59-mm7      3       92      81.5    12.6    6.5     1.18
2.5.59-mm8      3       115     67.8    35.2    18.3    1.46

And this load which normally changes little has significantly different 
results.
