I've slurped in a big file using File::Slurp but given the size of the file I can see that I must have it in memory twice or perhaps it's getting inflated by being turned into 16 bit unicode. How can I best diagnose that sort of a problem in Perl?

The file I pulled in is 800mb in size and my perl process that's analysing that data has roughly 1.6gb allocated at runtime.

I realise that I may be wrong about my reason for the problem but I'm not sure the most efficient way to prove/disprove my theory.
