Profiling edit

Profiling is, in a nutshell, assessing how quickly the various parts of your program run. Most often, you'll want your program to run fast, and using a profiler to find slow spots can help you decide what needs work. There is a simple profiler package included in tcllib: http://tcllib.sourceforge.net/doc/profiler.html

Profiling Tcl has more on the subject.

• DKF: That link is dead. I've recovered the file out of the Internet Archive and put a copy here as a temporary measure, but I don't plan to be involved long-term. I have put it up on github as well.

Paradyn is a performance measurement tool for parallel and distributed programs. Paradyn uses several novel technologies so that it scales to long running programs (hours or days) and large (thousand node) systems, and automates much of the search for performance bottlenecks. It can provide precise performance data down to the procedure and statement level.

Paradyn uses Tcl/Tk for scripting and GUI.
