If you have an OS X box to work on, then you have a handful of really excellent tools. Have a look at Shark from the CHUD tools (in / Developer/Applications/Performance Tools) Although it's sampling- based (.i.e. no need to gprof - just run sample running R), it is remarkably accurate and has ton of features for what they call 'data mining' of the profile data - including drill-down to source code and even assembly level. You can read a bit at http://developer.apple.com/tools/sharkoptimize.html It proves to be really useful and very flexible.
