Monitoring PHP Performance and Diagnosing Bottlenecks

Last week, we took a quick look at PHP-FPM, reducing process manager (PM) overhead and maxing out PHP-FPM’s throughput by attempting to keep processes in-memory using pm.static. However, beyond development server benchmarks, on our production servers, we also want to drill down into all services and components called up by each user’s interaction. This allows us the opportunity to diagnose PHP and other […]

PHP Benchmarks: OPcache vs OPcache w/ Performance Tweaks

A few weeks ago I wrote a short article which highlighted GUI solutions for monitoring and controlling PHP OPcache. We all know that enabling PHP OPcache provides massive performances gains (see benchmark graph at the end of article). In addition, since PHP 5.5, OPcache is now enabled by default. With these facts in mind, is it possible […]

The extension is built-in for PHP 5.5+ …but, if you are looking to improve PHP performance, the first step should be to use PHP 7+ which […]
