kommesel has asked for the wisdom of the Perl Monks concerning the following question:
I have a huge array (in the area of gigabytes)
and I wish to loop over (with foreach and the like)
However, once I loop over an element I have no need for it. It's quiet
tempting to use shift at each iteration to shrink
the array and save memory. However, the overhead of resizing
the array may cause an overall degradation of performance in
comparison to just looping over the huge array.
Can anyone give me any definite answer as to which
will yield more performance (or how can I emprically check
it)?
P.S.
The workstation will use swap files for sure
