prof question

[Spencer W. Thomas]

4.2Bsd comes with gprof, which will count time spent in sub-function
calls into the time for a given function.  In fact, it has a very fancy
time distribution function.  Furthermore, it tells you the call graph
for your program (i.e., who called who, and how many times).  Much more
useful, in many circumstances, than prof.  It was described in a paper
in SIGPLAN (I forget exactly, but it was a conference proceedings, in
1982, I think).
