For some reason, he ran "ab -c1" instead of "ab -c10", while nginx may
run perl in 2 workers on Core2 Duo (if worker_processes are 2). I believe,
it will twice the benchmark result. Second, he still mosty tests TCP
connection establishment via localhost instead of server speed. Why
he can not run the benchmark with keepalive ?
