Hi Mat,

Shouldn't be too different, at least to see which works best for you,
and as Tim said, it works with Core.

:) Well, I haven't used db.r, but I just glanced at it and it loads
each line individually it seems, and creates just an empty block to
load them into as a starting point. If loading the database is what's
slow for you, just changing those things might help quite a bit. Also,
if doing lots of inserts deletes, using a list! would be faster for
that. It does a linear search to delete a record, so that could
probably be sped up as well. Same for update. Selecting records could
probably be sped up as well, but I'd have to spend more time to see
what he's actually doing.

Gotta profile it to be sure, unless you already know exactly what
parts are slow about it.

For 50K records you probably want a true DB.

Dunno. I've heard that MySQL can peform pretty well and I'd have to
guess that not many big folks would use it if that was as fast as it
went.
