io_load:
Kernel                  Time            CPU             Ratio
2.4.19                  216.05          33%             3.19

2.5.39                  216.81          37%             3.20

mem_load:
Kernel                  Time            CPU             Ratio
2.4.19                  105.40          70%             1.56
2.5.38                  107.89          73%             1.59
2.5.38-mm3              117.09          63%             1.73*
2.5.39                  103.72          72%             1.53

Things to note:
Despite the new deadline scheduler, performance under IO load is worse than
2.5.38-mm3 (something else?)

Asterisks are placed where the difference was statistically significant from 2.5.39

Hardware: 1133Mhz P3, 224Mb Ram, IDE ATA100 5400rpm drive, IO load on same drive
as compile.

*NOTE* New version of contest means results are not compatible with results of
0.3x. Process Load now more of a process load (and less of a cpu load), and
changed priming (memory flushing) prior to each test results in far greater
resolution of results - hence the notable change in even noload results.
