HotShot has had some attention, and has been found useful, but I don't think of it as really finished.

What's missing from hotshot is a little script that makes it possible to use hotshot from the command line (just like profile.py), i.e. something like this:

import sys, os.path, hotshot, hotshot.stats

prof = hotshot.Profile("hotshot.prof") filename = sys.argv[1] del sys.argv[0] sys.path.insert(0, os.path.dirname(filename)) prof.run("execfile(%r)" % filename) prof.close() stats = hotshot.stats.load("hotshot.prof") stats.sort_stats("time", "calls") stats.print_stats()

The biggest problem I had with hotshot is the filesize. I was using the above script to profile a script which normally runs for about 10-15 minutes. After ca. 20 minutes the size of hotshot.prof was over 1 gig. Is there any possibility to reduce the filesize?

Bye, Walter Dörwald
