any other process could also be interfering with the resultant durations reported.

But profiling (using any of the available perl profilers) won't delineate the affects of those others processors, so won't add to the information available.

I too suspect that this will turn out to be the limiting factor in the OP's case. But it is just an guess at this point even if an educated one.

I would say that:

  1. given the structure of the main loop;
  2. and that the child processes exit as soon as they have run their respective subroutines;
  3. And the full code of those subroutines is supplied.

Unless the OP is deliberately hiding something from us; there is simply no scope for this to be anything other than an IO bound process.
