does not allow so at the moment, I think the limit is 2.5G including all
ram usage, correct?
The reason for such a big cache is because we have a 3 GB database, with
about 300 constant users, and performance is very important, we have
tried all other options (Classic, 32bits, 32 bits on 64 bits OS) with

is much faster than any other option. We have a 16 Gig ram server, 2
quad cores Intel, and 1 firebird server installed on each different
processor (8 firebird servers on the same machine), each server takes
care of a different database.
