If you are using an external database, this is really not a zope
question at all.  It comes down to how fast the database can prepare and
execute the query.  And this depends on all sorts of database
optimization, on system RAM, probably filesystem layout, etc.

Note that the ZSQL methods typically simply send a query as a string to
the database system.  They do not generally do prepare operations,
stored queries, etc.

This sounds like the kind of situation where you do want to use an
external database.  I have nothing nearly that large.  The largest I
have is about 64,000 records.  But, I see no zope-related bottleneck.
