If there is a large number of underlying domains and the topology of each changes frequently, it is likely that the Global Manager will often be required to perform multiple concurrent topology synchronizations.
To optimize Global Manager performance, it is best to reduce the number of small discoveries, and instead have a smaller number of larger discoveries. Also, if full rediscoveries are scheduled, Global Manager performance can be improved by staggering the times of full rediscoveries of the underlying domains.
Finally, if you expect a constantly changing network with a large number of discoveries, you may want to reconsider your Global Manager configuration. If you are not already planning on implementing a hierarchical aggregation Global Manager configuration or hierarchical mesh Global Manager configuration, consider using one of these configurations. “Determine the Service Assurance configuration” on page 36 provides additional information.
