Why is PHP-FPM faster than mod_php?

Configuration of php-fpm can be configured much better than the mod_php version, which gives you more control over the process. Also your PHP processes may run using a different user. You can even run multiple php-fpm instances (on different ports) which allow you to run multiple php versions at once.

How does FastCGI work?

Basically, FastCGI is a program that manages multiple CGI requests within a single process, saving many program instructions for each request. Without FastCGI, each instance of a user requesting a service causes the Web server to open a new process that gets control, performs the service, and then is closed.

Is PHP-FPM better?

PHP-FPM is faster than traditional CGI-based methods, such as SUPHP, for multi-user PHP environments. It does not overload a system’s memory with PHP from Apache processes. PHP-FPM features include: Ability to start workers with different uid/gid/chroot/environment and different php.

What is CGI mode for PHP?

What is the difference between CGI and FastCGI?

FastCGI is a newer web technology, an improved CGI version as the main functionality remains the same.
