PHP benchmarks: The state of PHP performance across multiple CMSs and frameworks

PHP 8.5 has now been officially released, and developers naturally want to know what kind of performance improvements they can expect across popular CMSs and frameworks.

To find out, we benchmarked 12 widely used CMSs and frameworks, including WordPress, WooCommerce, Drupal, Joomla, Laravel, and CodeIgniter, on PHP 8.2, 8.3, 8.4, and 8.5 under identical conditions. WordPress was also tested on PHP 7.4, since a notable share of sites still run on that version.

Our intention is to provide a clear, practical look at how performance shifts across recent PHP releases and what you can expect when upgrading.
