You should really be doing this anyways. One of the easiest ways to do this is to download a pre-made vmware player server application. Or you could do the xampp thing. Once you have that you can use xdebug [1] to profile your code. It has a lot of various ways of profiling. It doesn't require you modifying your code at all. Then it generates these files that you can use kcachegrind/wincachegrind to see every single function your script calls, how long it took, etc. There's also another tool to view these files called webgrind[2] [1] http://www.xdebug.org/docs/profiler [2] http://code.google.com/p/webgrind/
