If you're talking about Firebird SuperServer on Windows than you'se suposed
to tie the FB server to 1 processor/core only. So, use CPUAffinityMask=1 to
use the first core only, or 2 to the second, or 4 to the third or 8 to the
fourth.

BTW, Firebird Classic performs a lot better on SMP boxes (and
CPUAffinityMask do not apply to it since it can use all processors/cores)
