Can you recommend Performance Analysis tools for PHP? [closed]

Answer 1

See SD's PHP Profiler. Measures frequence of execution across your entire application and provides a hotspot graphical display of highly-executed code. No changes necessary to PHP server to install this.

Answer 2

Xdebug profiler is pretty good but the CacheGrinder can be a little difficult to interpret.

Zend Platform (expensive if you're not running the developers license) will alert you to issue code and bad use of resources.

Answer 3

Try webgrind. It gives you the profiling of CacheGrinder in an easy to read, browser based format. I'm on a Mac and it has made profiling a breeze.

Answer 4

XDebug's profiler is good. But then I'm a KDE user... I think you could install the KCacheGrind in other window managers though.

Answer 5

I'm personally a fan of XHProf, one of Facebook's open source initiatives. This, along with the XDebug dumps, is crucial in determining performance bottlenecks. Plus, the UI (and particularly, the weighted image-based callgraph functionality) rocks.

I have used this across the Gawker Media network in the past (again, along with XDebug-style dumps), to help focus our performance-geared development efforts.
