Perl Hashes, ever wonder about size/efficiency

Perl Hashes, ever wonder about size/efficiency
I've always wondered about the efficiency of using perl hashes, since it's one of the reasons we actually use Perl <G>

I found this:


And the original blog post that was referenced in the message, about the overhead a perl hash uses, and how the overhead for small keys/values can really eat up memory far and above what you'd ever expect.

For GLinks, with relatively LARGE hashes, it's not as much of an issue, but if you were using large hashes of small data sets, a huge amount of "silent" waste can occur.

I thought it was interesting, from a programming and "what's really going on" point of view.
