Does not really matter for Firebird, since API does not have batch
support. That means that driver emulates batches by sending commands one
at a time.

What is your transaction setting? Do you manage transactions by yourself
or you work in auto-commit mode?

That is good - it reduces the number of database roundtrips.

Nope. The most important thing is the transaction management - commit is
quite expensive operation. I would even increase from 50 records per
batch to something between 1000 and 10000.
