retrospective ;;Quote: gprof combines call graph arcs with program histogram data for elapsed time, call counts, and time per subroutine
retrospective ;;Quote: gprof has problems with skewed times and mutual recursion; fix by gathering complete call stacks; requires walking the stack
52 ;;Quote: gprof uses call site as primary hash key and callee address as secondary key; 5-30% overhead; no planning required
53 ;;Quote: problem of profiling under time-sharing; gprof samples the program counter to infer execution time
