I assume you mean the act of running queries to get the data for the
report reduces performance rather than the printing itself?

You mention nothing about the server hardware. It takes resources to
run queries, and if the I/O subsystem is not up to scratch, then the
performance is not going to just fix itself.

You have not mentioned the Firebird architecture you installed, but
for SMP machines such as this, Classic allows the different
connections to use different processors which can help for CPU bound
queries.

You will probably want to consider the query that is run by the print
job to make sure it has appropriate supporting indices. A 486 can run
a query faster than the latest quad core processors if it uses a
significantly better plan.
