Thank you, I will look into it. But I think the problem starts with the first problematic function (as the name suggests :)) - gene_to_legal_range.

When I next just before it I run 6 times faster than if I next just after it (~4 seconds compared to ~27 seconds for 50 iterations). This subroutine really looks simple to me, so I don't see why it has to take so much time (subroutine overhead?!).

p.s. I now run my home PC and the benchmarking results are a little different (but the relative differences are similar).

UPDATE

Almost always the sort is done on an array with a single element (there are cases where there are more). I even tried removing the sort at all, just to see the effect on running time - there is no change.

But, again, I suggest we start with the first, more simple subroutine. Is it really just perl subroutine overhead? Is there anything I can do about it?
