Back to mruby, the initial timer based profiling doesn’t have many of the advantages of callgrind, or other profiler tools. Adding timers was a manual process, it provided very coarse information, and it provided only a limited slice of the whole program. As such, a full mruby VM profiler should be preferred. The mruby-profiler gem is one such tool.
