see firebird.conf:
# ===========================
# SuperServer Engine Settings
# ===========================
#
# ----------------------------
# Which CPUs should be used (Windows Only)
#
# In an SMP system, sets which processors can be used by the server.
# The value is taken from a bit map in which each bit represents a
CPU.
# Thus, to use only the first processor, the value is 1. To use both
# CPU 1 and CPU 2, the value is 3. To use CPU 2 and CPU 3, the value
# is 6. The default value is 1.
#
# Type: integer
#
#CpuAffinityMask = 1

So Firebird SS (SuperServer) doesn't know to work with multi cpu-s
but Firebird CS (ClassicServer) does.
