I haven't spent a lot of time with SQLite in Rev so I can't comment and
that and look forward to feedback from others on that front. But FWIW
in most general areas I find performance in v4.5 to be on par or
slightly better than in v4.0.
One think I recently discovered is how so many things related to screen
updates slow to a crawl the moment you use any controls with graphic
I've submitted a proposed solution to the RQCC for regaining the lost
But unless you changed any objects between those two versions so that
