at first, thank you all for you nice help and very good tipps!

now, its unbelivable....
i have optimized p.e. windowsXP prof., and set in controlpanel, system,
performance-options,
(sorry i have the german version), optimal performance for processplaning to
BACKGROUNDProcesses.
You have the choice: Programms or Backgroundprocesses

My thinking was: Firebird is running as a SERVICE and started with SYSTEM,
and is a backgroundprocess!

But as i changed this to: Programms, the slow connection was gone !!!!!!!

NEVER SET THIS PERFORMANCE OPTION TO BACKGROUNDPROCESS!

Now i have a connection-time between 1-2 seconds, and this is very okay ...
Before it was 7 till 16 seconds

best regards
