Re: Kaffe/Jigsaw
Here is a little bench.
this test is using ptester, running on an ss20/SunOS5.5 and
Jigsaw running on a P90/Linux 2.0.25
With Kaffe-0.6.0 JIT
ptester -h138.96.152.39 -p8007 -c5 -k5 /test1k.html /test4k.html

So, a JIT improves the performances ;)
I made more or less the same test with Kaffe on sparc/solaris (without
JIT) and the result was... the opposite! Kaffe was two time slower than
Sun's VM.
Of course it is just a fast test. i didn't set up the optimal
configuration for jigsaw performance ;)
