1. You have an InterBase configuration file, but all of its configurations are commented out, anyway. How are you setting the page cache and how big is it?

2. You say that you are running IB 6.0 **but** those statistics were taken from a Firebird 1.5 database (ODS 10.1). What exactly is going on there? You are running IB 6 but using Firebird to do your restores?

3. Were any users logged in when you took these statistics?
