NGINX tuning for best performance

Moved to git repository: https://github.com/denji/nginx-tuning

NGINX Tuning For Best Performance

For this configuration you can use web server you like, i decided, because i work mostly with it to use nginx.

Generally, properly configured nginx can handle up to 400K to 500K requests per second (clustered), most what i saw is 50K to 80K (non-clustered) requests per second and 30% CPU load, course, this was 2 x Intel Xeon with HyperThreading enabled, but it can work without problem on slower machines.

You must understand that this config is used in testing environment and not in production so you will need to find a way to implement most of those features best possible for your servers.

Bash Script as alias of "mail" using "ssmtp" in ubuntu. Main purpose is sending mails via munin by ssmtp instead of postfix.
#!/bin/bash
# mail syntax: mail -s "any mail subject string" [email protected]
# or: mail "any mail subject string" [email protected]
if [ $1 == "-s" ]
then
subject=$2
recip=$3
else
subject=$1
recip=$2

# Set max to 16MB for 1GE and 32M (33554432) or 54M (56623104) for 10GE
