simple 4mb buffer proxy benchmarks

the goal: to do fast virtual host routing, e.g. to have a single process on a machine listening on port 80 and proxying data based on HTTP Host to other non-port-80 web processes on the same machine

many people use nginx for this because nginx is faster than node is currently for data-heavy applications (see below)

about these benchmarks

they use the JS proxies from https://github.com/substack/bouncy/tree/master/bench
