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

2.5.59-mm7 5 78 96.2 0.0 0.0 1.00

2.5.59-mm8 3 76 97.4 0.0 0.0 0.96
process_load:

2.5.59 3 92 81.5 28.3 16.3 1.16
2.5.59-mm7 3 95 77.9 33.7 18.9 1.22
2.5.59-mm8 3 195 37.9 205.3 60.5 2.47
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:
Kernel [runs] Time CPU% Loads LCPU% Ratio
2.5.59 3 98 80.6 2.0 5.1 1.24
2.5.59-mm7 5 96 80.2 1.4 3.4 1.23
2.5.59-mm8 3 99 78.8 2.0 5.1 1.25
xtar_load:

2.5.59 3 101 75.2 1.0 4.0 1.28
2.5.59-mm7 5 96 79.2 0.8 3.3 1.23
2.5.59-mm8 3 100 77.0 1.0 4.0 1.27
io_load:
Kernel [runs] Time CPU% Loads LCPU% Ratio
2.5.59 3 154 48.7 32.6 12.3 1.95
2.5.59-mm7 3 112 67.0 15.9 7.1 1.44
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
list_load:
Kernel [runs] Time CPU% Loads LCPU% Ratio
2.5.59 3 95 80.0 0.0 6.3 1.20
2.5.59-mm7 4 94 80.9 0.0 6.4 1.21
2.5.59-mm8 3 98 78.6 0.0 6.1 1.24
mem_load:
Kernel [runs] Time CPU% Loads LCPU% Ratio
2.5.59 3 97 80.4 56.7 2.1 1.23
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.
