I don't have experience with gperftools, but on recent linux kernels,
you can also use perf, which can't be made easier to use (no runtime
support needed), but you need a 'recent' kernel


I am hoping to talk a bit about those for our diving into numpy c code
tutorial in June, what's the + of gperf in your opinion ?
