Optimal PHP-FPM config values based on system configuration and load

Important

Since v2.0 only Linux is supported.

This package determines the number of system CPU cores, available RAM, and average RAM usage per PHP-FPM pool worker process. It then calculates the opinionated optimal values for PHP-FPM pool configuration, such as:

• pm.max_children
• pm.start_servers
• pm.min_spare_servers
• pm.max_spare_servers

Don't forget to keep an eye on your php-fpm.log to avoid failures!

Installation & Usage

Important

Ensure that your server is operating normally and serving incoming requests before executing the package command. This command takes into account the available RAM and the average RAM usage per PHP-FPM pool worker process to calculate values.

The most simple way to get the optimal PHP-FPM config values suggestions is to run the following command:

sh <(curl -s https://raw.githubusercontent.com/plakhin/fpm-optimize/main/suggest-fpm-config-values.sh)

Laravel

Also, you can install the package with composer as a dependency to your Laravel 11+ project:

composer require plakhin/fpm-optimize

Once installed, you can run php artisan optimize:php-fpm command to see the suggested php-fpm config values.

Additionally, this package adds php-fpm config values suggestions into optimize Artisan Command output.
If you don't want this behavior, simply set FPM_OPTIMIZE_INJECT_INTO_ARTISAN_OPTIMISE_COMMAND=false in your .env file.
