CiscoWorks NCM can be network intensive, therefore, if you have many virtual machines sharing a
virtual switch and network interface card, you could experience unexpected behavior, including

Significant performance degradation has been seen on ESX servers running multiple virtual machines
where one or more virtual machine was under heavy load. It is critical that the ESX server running
CiscoWorks NCM in a virtual environment be properly resourced to avoid performance degradation.

Note
The number of managed devices does not have as significant of an impact on performance as the number
of concurrent tasks. If performance issues are seen, reduce the number of concurrent tasks and ensure
that CiscoWorks NCM is getting the appropriate resources.
