The real source of your performance problem is the fact that Superserver
engine (in FB v1.x and 2.0 -- FB v2.1 has had more work done on the
scheduler) does a lousy (v1.x) or poor (v2.0) job of "time-slicing"
between a larger number active connections.

You should investigate the Classic engine, it is:

- much fairer in responding to requests from multiple connections
- the only current solution which provides any SMP (multi-processor)
support


Sean

P.S. Please remember to change the database cache settings when using
Classic (vs. SuperServer)
