I took my own advice and ran 'valgrind --tool=callgrind' on my tor server. The resulting callgrind file can be found at http://interloper.org/tmp/tor/callgrind.out.23678.gz.

For example of a pretty graph, this is the callgraph of tor starting, http://interloper.org/tmp/tor/2009-02-27-tor-callgrind-0.png -- Andrew
