The performance doctor, automatically

In the computing world, people are always talking about improving the performance of their computer code.

So what could be more helpful than a program that acts as an automatic "performance doctor"?

According to the PerfExpert 2.0 website:

PerfExpert automatically analyzes the performance of programs and suggests optimizations to alleviate the identified bottlenecks. It is intended to make performance assessment easy while providing accurate diagnoses of core, chip, and node-level performance bottlenecks. Because of this focus, it suffices (and is recommended) to use scaled-down data sets and resource configurations to obtain accurate analyses.

Sounds useful to us. What other tools are there out there like PerfExpert? Tell us in the comments!
