Firebird's support for multi-processor machines has been improved. Much of
the documentation describing plans to improve the support are not dated.

Is there a performance benefit to deploying Firebird on a multi-processor
machine? If so, what kind of performance gains have users experienced. Do
the different versions (i.e. Linux, Windows, Super-server, Classic) have
different multi-processor capabilities?

Thanks.
