HOW TO
This document deals with improving performance for sites utilizing ArcMap Server (ArcIMS 4.0 only). It focuses on changes that can be made using ArcIMS administration tools.
Note: The performance of ArcMap Services also depends on the composition of the map itself. The ArcGIS Desktop help topic "Creating interactive maps" offers advice on optimizing map composition for interactive use (serving on the Web or creating a published map file to be read in ArcReader).
To optimize performance in an ArcMap Server implementation, the following actions are recommended:
1) Activate recycling of the Spatial Servers.
2) Reconfigure Spatial and Virtual Servers so that ArcMap Services run separately from other ArcIMS services and use single instead of multiple instances.
Recycling is essentially the automatic restarting of Spatial Servers at user-configured times. By recycling the Spatial Server, system resources will be refreshed. All services associated with the Spatial Server will be unavailable during the recycling process. This includes all Virtual Servers (FeatureServer, MetadataServer, ImageServer�) associated with the Spatial Server. The recycling option provides a delay parameter so that if more than 1 Spatial Server exists one remains active while the other is recycling. It is recommended that at least 1 additional Spatial Server be available if activating the recycling feature.
Unlike other ArcIMS components, such as standard Image Server, testing has shown that ArcMap Server performance increases with multiple servers each using single instances. Changing the Spatial/Virtual Server associations of the site so that ArcMap Services are handled separately from other ArcIMS services enables the instance value for ArcMap Services to be changed to one without affecting the instance value for other services.
Note:
Keep in mind that each additional server will result in additional RAM needed to run the services.
