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. My criteria for good software: Does it work? Can someone else come in, make a change, and be reasonably certain no bugs were introduced?	[reply]
