On Windows, for Superserver, this parameter needs to be set so that the
entire service runs on one CPU. If it is set for multiple CPUs, you get
the "see-saw" effect, where Windows will swing the entire process from one
CPU to the other when CPU usage reaches capacity on one CPU.

It shouldn't be a problem for you if you didn't fiddle with the default
cpu_affinity parameter in firebird.conf, which is configured to the first
processor.
