[5.0.1-dev] Testing with JRockit 8

[Remy Maucherat]

For my book, I have been testing Tomcat with JRockit.

I tested on a Win2k / Linux dual boot box, so it has the advantage of allowing to compare OSes :)

The result:
- on Windows, its performance was pretty much amazing (it *did* actually beat IBM on Linux, which was previously making Windows look really bad).
- on Linux, it locks up the computer after a few requests and I have to kill -9 all Java threads individually (why ?).

I don't think there's a problem with Tomcat which would cause that. For the record, I was using RH 8 with the latest kernel patch (the one Costin says is bad in his weblog ;-) ).
The main disadvantage of JRockit is its insane memory usage (basically, it's 2* Sun Hotspot client; maybe there will be a use for those Athlon 64s even for small servers after all ;-) ).

The other result is that Tomcat on Linux appears to run more reliably than Tomcat on Windows (except for the socket lingering "bug" that did cause problems), as on Windows, with all VMs, a few connections are rejected (while it never happens on Linux). I don't believe this behavior is caused by a Tomcat bug.

Any comments, or anyone able to reproduce this ?

Remy
