George just released the notes from his php|works presentation about PHP Profiling and also comitted a fix for my problem with APD.

I started profiling Serendipity 0.8-alpha2 with XDebug a few days ago, and can now finally move on to using APD.

I also installed Turck MMCache on my home server (this server), to speed up PHP opcode. I had no idea you could speed up PHP that much by installing an opcode cache, it’s quite impressive.
