Here are contest (http://contest.kolivas.org) benchmarks with the dedicated
osdl (http://www.osdl.org) hardware for 2.6.0-test4 and mm2. mm2 includes my
O18.1 scheduler tweaks.

There is virtually no change between 2.5.75 and 2.6.0-test4 (which is expected
and desirable) apart from the nice increase in the amount of work done by
mem_load without any hit to the concurrent kernel compile.
There is a small prolongation of time under process_load (process_load is 16
tasks and the kernel compile is 4) but with an appropriate improvement in
work done by process_load and no wasted cpu time.
Conversely there is a significant drop in time under dbench_load (dbench 16 vs
make -j4) with equivalent cpu usage.
Otherwise slight shifts in the balance only.
