CPU usage isnt all that counts... I can write an http server, that uses 0.1%
CPU time and produces 800bit/sec traffic... :-)

I just cant find the thread about apache/thttpd (it was in
freebsd-performance@, I think), and I dont have up-to-date hardware, and I am
too lazy to compare Apache on FreeBSD to the theoretical maximum, some piece of
software can reach on FreeBSD...

Since these systems are nowadays so complex and difficult to compare, I would
recommend benchmarks, that r tailored on and for the special box... Ideally one
would use different boxes and test each with different OSes and different
application-implementations, so that u can do an informed decision based on
empirical data in the end (of course I know, that limited time and funding
causes some pressure)...
