Xdebug will make your site slow

[Jonathan Lahijani]

Some time ago, I decided to install xdebug on my development server, but I never really needed it or used it.  TracyDebugger is enough for what I'm doing.

I didn't notice it then because my app was not highly developed at the time, but it really causes speed issues especially if you're working on a sophisticated site with a lot of business logic.  For a long time, I thought it was just ProcessWire itself being slow, my app being slow due to some optimizations I hadn't done yet, my database being very large, combined with my low spec dev server, but it turns out disabling xdebug, which I had long forgotten about, made things much faster.

Just a heads up if you're having speed issues!
