Performance

Performance tests

The system boundaries are hard to define, as they depend on many factors, such the boundaries of
the hardware performance in general, the network performance, the "traffic" created by the
application, concurrent polls from Supervisors, Station Save intervals, Recovery Service intervals,
etc.
In addition to the general Tridium guidance of a maximum of 80% CPU load, Honeywell has
undertaken two exemplary performance tests.
The maximum recommended CPU usage is outlined in the two tables below.
