11-8 Performance and Capacity Specifications
(5)
While using the NI FBUS Configurator, you can only monitor 1 Linking Device at one time. This
application should only be run on the Backup Server (if redundant) as this will put an additional CPU load
on the system approximately 35% higher than your normal running state. If run on a Non-Redundant
Server, it is required that you have a more performance CPU configuration.
(6) RSBatch includes multiple services and applications.
(7) This upgrade requirement is per Server Node.
ATTENTION
!
Low memory and CPU resources can affect Server
performance in the following ways:
•
Low memory can impact CB and Station
operations such as display call-up and screen
refresh. Background applications such as RSLinx
and CDA can also be impacted. On occasion,
extremely low memory resources have caused
foreground and background applications to fail.
•
Low memory causes virtual memory to be
swapped often, which itself is a CPU intensive
operation. Therefore, low memory directly affects
the amount of available CPU resources.
•
Low CPU resources can impact communication
between Clients and Server. Although the
communication subsystem guarantees data
delivery, low CPU resources can create
communication bottlenecks that adversely affect
the freshness of data displayed.
•
Low CPU resources can impact CB operations
such as: opening charts, loading, uploading and
updating project.
