Building High-Performance APIs with PHP 8.4 and Swoole

PHP at the Speed of Light

When developers think of high-performance, asynchronous web servers, they usually think of Node.js or Go. But in 2026, PHP powered by Swoole is outperforming traditional frameworks by orders of magnitude.

What is Swoole?

Swoole is an event-driven asynchronous & coroutine-based concurrency library for PHP. Instead of booting up the entire framework for every single HTTP request (the traditional PHP-FPM model), Swoole keeps the application in memory, allowing for massive throughput and websocket support.
