First benchmark results

A benchmark have been done for Fetcher/Apache-ILU using HTTP/1.x stacks.

HTTP/1.0 stack from ILU is as efficient as the native one, but eat more CPU
HTTP/1.1 test has been conducted but wasn't Ok (no pipelining, new connection on each request)

New benchmarks have to be conducted, especially with the NG stacks, not the standard one.

However this improved the confidence on the current code base!
