worker_processes auto;
worker_rlimit_nofile 100000;
error_log logs/error.log crit;
events {
 use epoll;
 multi_accept on;
 worker_connections 4000;

À noter que le nombre de requètes/s dépend de l'ordinateur utilisé. Et aussi que "ab" est mono-threadé et est donc limité en performances (htstress -n 200000 -c 10 -t 8 retourne 85595 requètes/s)
