What is PHP-FPM used for?
Q: What is PHP-FPM used for? A: PHP-FPM (FastCGI Process Manager) is a web tool used to speed up the performance of a website. It is much faster than traditional CGI based methods and has the ability to handle tremendous loads simultaneously.
How does PHP-FPM work?
As PHP-FPM receives a proxied connection, a free PHP-FPM worker accepts the web server’s request. PHP-FPM then compiles and executes the PHP script, sending the output back to the web server. Once a PHP-FPM worker finishes handling a request, the system releases the worker and waits for new requests.
Is PHP-FPM necessary?

Should I use PHP or PHP-FPM?

“but php-fpm suppose to be much faster because it’s using FastCGI ” — fastcgi is just a SAPI, it does not make php itself faster or slower. But presence of fastcgi makes request transfer slower – since you need to connect and transfer a request, whereas with mod_php it’s in the same process memory space.

- max_children – This is used to set the total number of processes allowed.
- start_servers – The number of child processes created on startup is defined by this.

Does PHP-FPM need nginx?
PHP-FPM is installed and active for NGINX. And that’s it, you’ve got NGINX up and running with PHP-FPM support.
