Classic and SuperClassic uses cores for multiple users,
SuperServer - use only one core.

But, if you use Classic or Superclassic, it does not guarantee
that you will have 100% CPU load.
RDBMS is not a calculator to load only CPU. RDBMS mostly cracks data.
And data is on disk or in memory.
So, if you have bad disk or memory I/O, CPU will mostly lower than
100%, because CPU load depends on what Firbird engine is doing to
execute your query.
