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
Running test: >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>

Actual test time.. 60 seconds
Total requests.... 3408 (56 requests/sec)
Total failed...... 0 (0 requests/sec)
Total bytes....... 9596176 (159936 bytes/sec)

With Sun's VM ported to Linux:

ptester -h138.96.152.39 -p8007 -c5 -k5 /test1k.html /test4k.html
Running test: >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>

Actual test time.. 60 seconds
Total requests.... 1986 (33 requests/sec)
Total failed...... 0 (0 requests/sec)
Total bytes....... 5409458 (90157 bytes/sec)

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 ;)
