I tried it FBServer is running with affinity 1 so it is on the first
logical CPU.
I called setprocessaffinity in my application to set the affinity to the
second logical CPU.
In the task manager I can see now that fb has affinity to CPU 0
and my app to CPU 1
during the transfer the CPU is at 0-5% and it's really really slow (as slow
as without setting cpuaffiinity
in my app).
I am still confused...
