How many worker_processes should I use in Nginx?

Answer:

In the Nginx configuration (nginx.conf), the default worker_processes is 1.

e.g.

worker_processes  1;

However, as nowadays most servers are multi-core/multi-processor machine, it is a waste to only use 1 worker process.

The recommended worker_processes is equal to the number of CPU cores, e.g. if you have a dual Quad Core server, you should set to 8.

worker_processes  8;
