Ok, if I use your FreeBSD figure of 410 and normalize it to the 166 seen in
the URL above (because of different hardware), it looks like the
Linux/Kaffe/jit/poll would be about 348 versus Microsoft's 1412.

Actually, I'm more interested in the amount of concurrent connections Kaffe
can handle - that test separated the men from the boys.

I'm not trying to be critical for the heck of it here.  I need to determine
viable platforms for my product, and performance is an important factor.
