Profiling heap memory usage on perl programs

Question

I have written a perl program to operate on huge datasets. I am trying to profile its excution in terms of its memory usage. Tried using valgrind on small datasets, but it slows down the execution dramatically. I am looking for just heap profiling. Could you guys suggest some ways ?

Answer 1

When I used Google and the search term 'perl memory profile', one of the first items points to the Perl module Devel::Size as one way of spotting memory usage. There are also memory leak detector modules lurking around.
