That introduces overhead and affects performance and timing
Dear salva,
Thanks so much for your important comment!
Does that also affect timing with Benchmark or Benchmark::Timer?
If so what's the best way to time the portion of your code without having have to add overhead.

    You can usually trust Benchmark (I don't know about Benchmark::Timer)... but it's not perfect either: Benchmark.pm: Does subroutine testing order bias results?

    Sometimes, timing the full program (or a script specially written for the ocasion) from the shell with time is also a good solution.
