I put together these pages to help others understand
what is in Andrea's kernels a little better.
http://home.earthlink.net/~rwhron/kernel/2.4.17rc2aa2.html
http://home.earthlink.net/~rwhron/kernel/2.2.20aa1.html
The pages are created from his patch diff logs.
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
----------------------------------------------------------------
OS fork exec sh

2.4.17rc2aa2 745 2769 9583
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.

Consider it bookmarked 8)
I hope you can find the time to keep up these tests,
as they should start to show some even more interesting
results as the various trees progress.

I'll second that, very nice that someone takes the time to do this.
