The ProDG debugger has come a long way and is easier to use and more powerful than ever; its integrated profiling is great for quick performance spot-checks.
When you need the heavy iron, Tuner can analyze the entire machine's performance across many frames of data, and is in my experience simpler to use and understand than the Performance Analyzer hardware.
