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.
