Troubleshooting PHP for performance

I have a pretty high load PHP application. It's gotten to the point where the system slows down dramatically every now and again. I would like to be able to trace it down to the offending scripts, however all I have is the process ID of the processes that are eating up the most RAM or using the most CPU. Any suggestions about going after performance optimization?

Use a profiling tool such as Xdebug.
