Three simple way to make apache FLY

1. Keepalive On

KeepAlive does one simple thing: destroy Apache's ability to handle many concurrent requests. Well, that and speed up existing connections by allowing them to download all assets before closing a TCP connection between a browser and your server

2. MaxClients

(Total RAM - RAM used for Linux, MySQL, etc.) / Average httpd process size.

Averahe HTTP process size = ps aux | grep 'httpd' | awk '{print $6/1024;}' | awk '{avg += ($1 - avg) / NR;} END {print avg " MB";}'

RAM used for mysql = ps aux | grep 'mysql' | awk '{print $6/1024 " MB";}')

3. AllowOverride

inside htaccess or virtual host (AllowOverride None.)
