Couple of tests I ran on Cocoon, VMs and JDKs

FYI, might be interesting for the Cocooners out there, as that's what 
I've tested.

Yep, I don't! :-) For VNUNET, our acceptor limit set on Jetty is (IIRC) 
15. So, only a maximum of 15 threads can access Cocoon at the same 
time.

We cache the bejesus out of the application, so parallelization of 
tasks is not "that" important to us, while raw speed definitely is.

FWIW, I tested threading comparing normal linux threads with NPTL, and 
there you definitely had a massive improvement by switching to NPTL, 
but more than that, I can't tell you...

I believe SIMILE runs on the same hardware, right (or was it a HP 
360/G3?) I think you can ran the tests yourself! :-P

Anybody done any comparisons between Java 1.5 and 1.4.2?

...Since Cocoon now compiles cleanly on 1.5.

Interesting.

It would also be kinda cool to have some other data in terms of 
concurrency, you are stressing with 10 threads, but it would be 
interesting to see if the 64bit architecture handles load better or 
worse (don't know why, but it's another axis to consider that you 
haven't in your exercise).

yes, I know you might not care :-)
