We have been working with a large and complicated perl program that
uses lots of memory (the resident set is up to 8 megabytes).  To try
to optimize it, we would like to find out which data structures are
using the most space.  Has anyone done this?  Does anyone know of a
good way to determine how much storage a perl array or associative
array is consuming?  The ideas that come to my mind are to either
write some kind of perl utilities to traverse arrays and find their
total size, or to compile perl with -g and use dbx to dig through
it's memory.  Any advice or suggestions would be appreciated.
