I seem to be using 4 MB, for no particular reason... I'll increase that to 20 MB
when I'm adding items to the db.

Question -- will a 20 MB cache require the end user to have a faster computer?
More RAM? Etc.

Another question -- should the cache be 8-20 MB just when I'm adding items, or
also 8-20 MB for playback on the user's computer? The database will always be
ReadOnly for playback. I want it to be as fast as possible, we're searching
>1000 fairly long articles (many pages each).

Good point. I looked at some of the #text members in Director and they are
around 5 or 6KB each. This is BEFORE they are put into Valentina. When I
retrieve them with getMedia(), the resulting #text member reports its size
around 278 or 279 KB (!). Not sure what's going on there.

I'll try 5KB since that's the average. Any downside there?
