Efficient PHP

PHP-FPM and OPcache: faster PHP execution

PHP-FPM manages PHP process pools, while OPcache keeps compiled code in memory. Together they reduce response time and server load for WordPress, shops and PHP applications.

What does PHP-FPM do?

PHP-FPM keeps PHP processes ready to handle requests, so the application does not start from scratch on every user visit.

What does OPcache do?

OPcache stores compiled PHP opcode in memory, so the interpreter does not repeatedly read and parse the same files.

When is the effect strongest?

It is most visible in CMS systems with many PHP files: WordPress, WooCommerce, PrestaShop, Joomla, Drupal and application panels.
