Surprisingly, it looked reasonable when I benchmarked it today.  Here
are the results:

Kaffe 1.1.5
250  users -- 205/sec throughput, 3.3 average, 0% error
500  users -- 307/sec throughput, 11.4 average, 0% error
1000 users -- 325/sec throughput, 370.7 average, 0% error
2000 users -- 138/sec throughput, 3048.8 average, 0% error

JDK 1.5.0
250  users -- 204/sec throughput, 2.8 average, 0% error
500  users -- 307/sec throughput, 42.2 average, 0% error
1000 users -- 390/sec throughput, 124.1 average, 0% error
2000 users -- 294/sec throughput, 130.8 average, 0% error

When the concurrency was high, Kaffe was quite a bit slower.  But,
at the low end, it seems to keep up with Sun JDK 1.5.0 just fine.
I did see some problems though: several webapps I tried didn't work
due to random misc JVM problems in Kaffe.  It's still looking a bit
incompletely implemented.

For the above test, I used jmeter CVS HEAD with Peter Lin's concurrent1
test plan (from http://cvs.apache.org/~woolfel/native_testplans.zip),
modified for my box's IP address, and to request /tomcat.gif.
The tested box is a Fedora Core 2 x86 32 box (running Tocmat 5.5.9).
The tester box is a Fedora Core 3 x86 32 box (running jmeter).

Remy: Maybe the slowness you saw with kaffe is on win32?
