The
following memory utilization represent average memory per instance
as calculated by dividing total database memory by the number of
instances. This simple mechanism would imply that on designs with
larger number of instances, the average memory would be even lower
as the fixed overhead of the library data would be spread across
more instances.
Use these numbers only as a guide line; real numbers may differ
on a case by case basis.
