[RFC] HTTP module benchmarks

Hi all,

I was interested how fast Kannel's HTTP server implementation is.
Mainly because we wanted to use it as a base for own applications to
be writen in C here at Wapme.

Here is a result in comparision against Apache 1.3.26, which does not
look to good for us. I thought we should be faster then the
full-fleatched default configuration of Apache, but we haven't.
