GNU/Linux offer a seamless way of profiling programs called perf.

Profiling is the task of investigating which parts of your program take the most time.

After your program is running, you need to identify it’s PID (e.g. with ps xa), and then call perf as:

sudo perf top -p 147792 -K

This will give you an interactive output similar to what is shown below which you can navigate with the keyboard:

This is a list of functions sorted according to the percentage of the time it is encountered by the profile sampler, which is thus proportional to the relative amount of time the function takes of the whole execution, compared to other functions. From this list we can get an intuition about which parts of the code should be optimized.

One problem with perf top is that it truncate symbols names, which can be quite large in C++ if templates are being used. An alternative to the above that preserve the full symbol names can be obtained with:

$ sudo perf record -p 88546

This should be run for a while to gather statistics, and then stopped with CTRL-C. The results can then be inspected with:

$ sudo perf report --stdio

Which gives an output similar to:

# To display the perf.data header info, please use --header/--header-only options.
