I meant... so slow compared to JDK 1.1.7.
I have a K6-II 350 with 128Mb of RAM, the JDK1.1.7 worked fine.

Oh, wonderful... yes, I noticed that there was a JIT included, but I hoped I
had to do something to activate it.
If the JDK1.2 using JIT at least twice as slow as JDK1.1.7 WITHOUT JIT, I think
I'll go back to JDK1.1.7 and now I understand why people ask for the glibc 2.1
version of the JDK1.1.7!

I'll do the test. I'm working on a graphic project, but also on a distributed
computing which involves millions of loops.

This is not true on my system!!!
JDK1.1.7 *without JIT* worked much faster than JDK1.2 with the JIT (any chance
to check if the JIT was actually activated?)

Yes... damn, it is a nightmare!
I get 11 java processes, each one with size 81512 (RSS: 24324).
How can this happen??
(No, I never declared any new thread, if you wonder... maybe the swing
components?)
