I'm trying to debug a PHP web application hosted in IIS from Eclipse using the Zend Debugger. Unfortunately whenever I start a debug session the web server becomes very slow in serving up the pages. So slow in fact that I often get 500 errors that prevent me from debugging at all.
I've traced back the 500 errors as coming from FastCGI timing out (50 secs) but there the trace ends. How can I figure out what makes debugging so slow and fix it?
Some more details:
- Zend Debugger properly appears in php -m.
- Both the IIS web server and the Eclipse IDE are on the same machine.
- This is my personal developer machine. I'm the only one using it.
- IIS 7.5 on Windows 7 Ultimate 64-bit
- PHP 5.3.3 VC9 x86 (nts)
- Zend Engine v2.3.0 with Zend Debugger v5.3
- Eclipse Helios Service Release 2 (with PDT), Build id: 20110218-0911
