In this video, we explore how to optimize the PHP Opcode Cache (Opcache) to improve the performance of a web server running multiple WordPress websites. By adjusting a few key settings in your PHP configuration, you can significantly reduce page generation time and memory usage.
We use a free GitHub script to visualize memory consumption and identify bottlenecks that occur when the default PHP settings are not enough to handle multiple sites.
Key Takeaways:
— Speed: Optimized Opcache can make your WordPress dashboard and front-end load up to twice as fast.
— Efficiency: Proper configuration can reduce the memory used per page request by up to five times.
— Scalability: Learn which settings to change to ensure all your plugins and theme files fit into the server's RAM.
