Benchmarks

Has anyone made any speed/CPU usage comparisons between TUX and Apache 
2.x?  I am especially curious about comparative flat file performance 
with the 2.6 kernel, TUX, and Apache with the worker MPM.  The last 
comparisons I've seen were between Apache 1.3.x on the 2.4 kernel.  
Since Apache 2.x uses sendfile(...) these days, I guess what I'm really 
asking about is the overhead of the context switch to userspace.

Nevertheless, for whatever reason...

How big a difference is there in CPU/mem usage, and how big a pipe do 
you need before the differences become significant?  If no one's done 
it, I'll have to do them myself;  But I figured that I'd check if 
someone else has done it first and save myself some time.
