Heise Online Reviews Drupal 11.3.0 Performance Gains
German technology publication heise online has highlighted the performance upgrades in Drupal 11.3.0, citing the integration of HTMX and PHP Fibers as key innovations driving faster rendering and lower server load.
The article, published on 18 December 2025, outlines how HTMX—now used in Drupal’s BigPipe—reduces JavaScript overhead by up to 71%, replacing legacy AJAX interactions and streamlining frontend behavior. PHP Fibers, introduced with PHP 8.1, enable cooperative multitasking that allows cache and database operations to run without blocking, improving response times, especially on cold caches.
According to independent benchmarks by MD Systems, sites with high database load see the most pronounced performance improvements. The article also notes enhancements to the Navigation module, CKEditor, and export tooling for developers.
