I have tried your ways but it doesn't work either. I tried the following:

1. Install Win2003 SP1 and adjust the TcpAckFrequency.
2. Change CPUAffinityMask
3. Install Firebird Classic Server

All the above combination doesn't work for me. The performance still
slow like snail.

However, if I install windows 2003 without domain controller.
Everything works like a champ. I didn't install SP1, Adjust
CPUAffinityMask. By install the Firebird SuperServer, I got the
performance I want. To my case, it is the Domain Controller that cause
the problem.
