OProfile has been used to find performance problems in Red Hat applications:

Fixing the performance problems identified by OProfile yielded about 15% reduction in the build time for mozilla on ia64 (wwc2003 paper). In the second URL OProfile identified a significant performance problem in the exception handling library used by gcj and yielded a much faster version of the Eclipse IDE.

Thank you, first I've heard of OProfile and the Intel price tag is nuts.
OProfile sounds like a real winner according to the Eclipse thread.
You're welcome. OProfile really helps identify the problem areas in code. There will be an article about OProfile in Wide Open Magazine (https://www.redhatmagazine.com/). The article optimizes dcraw which converts raw image files from a digital camera into Portable PixMap (PPM) files.
