in reply to Expanding Two demensional arrays

Use DBM::Deep. It will be slower than RAM, but it won't cause your script to go into swap.
My criteria for good software:
  1. Does it work?
  2. Can someone else come in, make a change, and be reasonably certain no bugs were introduced?

    I concern for this sentence from synopsis "A unique flat-file database module, written in pure perl." Is this efficient?

      Yes, it is efficient. It's not fast. It does several things that no other DBM (that I know of) does:
      • It handles nested Perl hashes and arrays to any level
      • The file is ftp'able across OSes and endian-ness
      • It is Pure-Perl, which means it's easily deployed on Windows
      • If you use the tie interface, you only make a change in one place in your program and the rest of your program thinks it's using a regular variable.

      Hence, given what I know about your problem, this sounds like a really good first-pass to see if memory thrashing is your root issue.
