Category : Programming Languages

We have one machine in-house that is 20 times slower starting our Delphi 7 app than any other machine.

profiling with g++

How to profile c++ code to get the call times and cost time of each line of the code, just as the profile tool

I need to implement execution time measuring functionality. I thought about two possibilities.


First - regular time() call, just remember time each execution step starts and time when each execution step completes. Unix time shell command works this way.
