Thanks Alan, this is good to know. This may also explain the
difference in speed - we pull in 80MB of data in a migration (300-400k
records), which used to take 50+ minutes and is now only 30 minutes
(however some queries seem longer ... maybe).

Anyway, I've been looking on the ibphoenix site for docs on
strategy/methodology for choosing the optimal paging size. I couldn't
find one (maybe I missed one) - do you know of any docs/links covering
this?

Thanks again
Phil
