How can I easily get fractions of timing for each nested function?

Consider a nested call like this:

Total[DigitCount[Mod[(2^10000) + 1, Prime[100]]]]

I don't want to assign each parameter to a variable and wrap Timing around it, but looking for a way to wrap the hole expression with Timing and get fractions of total time for each function.

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

Related questions: profiling-from-mathematica, and workbench-profile-question. Not fully sure, but this one may be a dupe of one of those. –  Leonid Shifrin Nov 25 '12 at 15:49

According to Leonid Shifrin recommendation:

Put your Mathematica session in debug mode by going to Evaluation->Debugger

F[x_] := Total[DigitCount[Mod[(2^10000) + 1, Prime[x]]]]

Table[F[x], {100000}]; // RuntimeTools`Profile

Well, thanks for ackowledging, but the recommendation was really not mine - I merely pointed to that discussion, the real credit goes to those who provided the answers there. –  Leonid Shifrin Nov 27 '12 at 11:32
