For nginx.conf file

Better to set worker_processes X number based on your CPUs. For finding number of CPUs type following command in shell

cat /proc/cpuinfo | grep processor

This will give you output like

processor : 0 processor : 1

So I have 2 cores. I'll put 2 (on many forums, sites I found they says put the double of your CPU. In my case it would be 4 but I found equal number to number of CPUs is best.
