Did the test involve creating the database from scratch?

If so, IB does not set ForceWrites = True by default. Whereas, FB does.
Setting ForceWrite = True make for a completely reliable db.

This would more that explain the timing differences.

All things being equal, FB v1.0 and IB v6.0 should perform exactly the
same. FB v1.0 just has a lot fewer bugs/crashes than IB 6.x
