Comments on: Faster PHP Apps - Profile Your Code with Xdebug http://www.sitepoint.com/blogs/2007/04/23/faster-php-apps-profile-your-code-with-xdebug/ Sun, 20 Jul 2008 21:03:11 +0000 http://wordpress.org/?v=2.5 By: MattC http://www.sitepoint.com/blogs/2007/04/23/faster-php-apps-profile-your-code-with-xdebug/#comment-233322 MattC Wed, 25 Apr 2007 03:23:04 +0000 http://www.sitepoint.com/blogs/?p=1907#comment-233322 I recently discover Xdebug and was blown away by it's profiling abilities. This article really only skims the surface and I think misses the point by suggesting query caching and APC as primary ways to improve performance.

Saves lot of time and Money. Yes Xdebug do output profiling data as like FireBug. Saves lot of time and Money.

I would tend to run Xdebug without APC on a development server anyway. Then the staging server would mirror the live production server as closely as possible, with APC but no Xdebug. Of course, these servers could all be on the same physical machine thanks to <a href="/blogs/2007/04/20/virtualization-save-time-money-and-sanity/" rel="nofollow">virtualization</a>.

Has this been rectified in recent versions (of PHP and/or the modules)? I can (and do) use xdebug on my development machine, but haven't been able to use APD.

Sometimes it is useful to look at the usage pattern over several requests. In order to do that, set <code>xdebug.profiler_aggregate = 1</code> in the .ini file, restart Apache, execute several requests, and then stop Apache. You will see a .cachegrind.aggregate file in the profiler directory. It should also be mentioned that Xdebug by default profiles only one request cycle.

Just as a small addition, PHPEdit supports xDebug and the profiling features since the new version is released.
