On http://developer.osdl.org/craiger/hackbench one finds hackbench.c
and the result that 2.6 is much better than 2.4 where scheduling is
concerned.

I was shown results that go in the other direction, so just tried
on a machine here.

50 processes
2.4.26:   24 sec
2.6.0t11: 72 sec
2.6.8.1: 120 sec

20 processes
2.4.26:    8.6 sec
2.6.0t11: 29   sec
2.6.8.1:  30   sec

This was on a 256 MB 400 MHz Pentium II.

In a 512 MB dual p3 machine I got this: (hackbench 100)

2.4.26: Time: 38.123
2.6.9-rc2-mm1: Time: 19.505

BTW, in the 2.6 case the kernel didn't have a very nice behaviour: A couple of
seconds after starting hackbench(after doing the benchmarks), Xorg stopped
running until hackbench finished. X was using nice 0.
