htop is an interactive system monitor and a process viewer, process manager, trace tool and more.

PHP Benchmarks: OPcache vs OPcache w/ Performance Tweaks

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