I've stress tested and benchmarked 2.4.17rc2aa2 a lot and
it's been very solid. For a workload that creates a lot
of processes 2.4.17rc2aa2 has a definite edge. This is
easiest to see in a couple unixbench tests:
2.4.17-mjc1 2.4.17rc2aa2 2.5.1-dj10
System Call Overhead 352361.7 362120.5 255809.4 lps
Process Creation 817.5 2037.7 1212.0 lps
Execl Throughput 265.8 458.4 316.5 lps
And lmbench; the highest and lowest results of 3 runs were dropped.
Processor, Processes - times in microseconds - smaller is better

2.5.1-dj10 810 3504 11.K
2.4.17-mjc1 1128 4244 12.K
Good stuff comes from a lot of sources, and I'm hoping some of
the tree maintainers will start cherry picking from Andrea's
tree too. :)
Note: mjc1 above was configured without preempt, rtsched
or lockbreak.
2.4.17rc2aa2 consistently does better at dbench too.
