No. Firebird has four configurations: SuperServer, Classic, SuperClassic,
and Embedded. SuperServer is a traditional shared server to which all
clients connect. Only one SuperServer can access a database at any one
time. The downside of SuperServer is that its threading model does not
support multi-processors. Classic has one process per connection.
SuperClassic is a shared server that does support multi-processors, but
each connection manages its own page cache. Embedded is for local access
to a database from a single client.

Look at firebirdSQL.org, though the question of configurations is so basic
that it's not covered very clearly - at least I couldn't find it.

Good luck,
