Besides the verbose and pretty output of Devel::NYTProf it is also quite more accurate than Devel::SmallProf!

    In what way?

    In the absence of evidence, opinion is indistinguishable from prejudice.

      The overhead introduced by Devel::SmallProf for every Perl sentence executed is too high resulting in a non-linear distortion of time measurements.

        I'd be interested to know more about the "non-linearity" if you have the time to explain further.

        But for the most part, the absolute accuracy of the timings is of little importance to profiling.

        The important factor is the relative timing, and the consistency those relative timings from run to run.
