The principal table in my database has about 550 records, with about 20
fields each. A number are binary in type, and two are memo, with the
rest being text or foreign keys. Almost all the memo fields are empty.

Just to move the record pointer from the first to the last record takes
almost exactly 20 seconds. To do a search of the beginning of the main
text field for a 6 character string that isn't there (i.e., the engine
searches to the very end of the table) takes 2 minutes and 5 seconds.
You can imagine how long it takes to locate and update 10 records. This
is the worst performance I've ever seen in a database, period.
 
It would help to know what OS you're on and whether the file is a
self-contained ODB file or if it's accessing an externally-served database.
 
I run a fairly large database (much larger than the one you're talking
about) on Windows XP without any problems, and have for years. However,
I do not have it as a self-contained ODB file; I use LO/OOo as the
front-end and serve the database using hypersql. I found that doing it
this way dramatically speeded (sped?) up the process. You might try
converting over to that model.
 
I have heard that H2 DB is actually a bit better for this purpose and
that it's not tremendously difficult to convert over to H2 from
hypersql, but I haven't had the guts to try it yet.
