GoKawiilQbix launches PHP server using fork-based workers to boost concurrency
A developer built Qbix, a PHP webserver that forks thousands of lightweight worker processes from a single parent process using pcntl_fork(), relying on the Linux kernel's copy-on-write memory sharing. Unlike FrankenPHP, RoadRunner or PHP-FPM, which are limited by worker count due to memory duplication, Qbix lets each worker share the framework's loaded classes and only pay memory costs for pages it actually modifies during a request.
