• How does upgrading CX-Supervisor affect communications
performance?
The graphs below show that this does not have an impact itself, which is
not surprising as a communications functions, and therefore performance,
are governed by the communication middleware: CX-Server. The graphs
show:
"Upgrading CX-Supervisor does not affect the total number of
Subscription points that can be simultaneously read, which has remained
more than 1000.
"Performance of instantaneous read and write is not significantly affected
by the version of CX-Supervisor.
"Updating CX-Supervisor does not affect how performance degrades
when the system gets busy.
Note: CX-Supervisor 1.2 and later do include automatic optimisations for
writing array elements that can yield substantial results, particularly with
serial communications. These performance improvements have been
excluded from these results rather than distort the true figures.
