Hi Thomas.

Thanks for your answer.

I use SuperServer.

Why? Performance. It seems to run faster.

Which Firebird server architecture are you using? CPU affinity is only for SuperServer and the question is why do you bother with SuperServer on a multi-core machine when there is Classic or SuperClassic available?
