Scope of virtual portals

IBM has tested an installation with 300 virtual portals and a total of more than 200,000 pages successfully. More detailed results of these tests are listed here.

• A IBM WebSphere Application Server 64-bit environment is suited best for a large number of virtual portals.

• For good results, we need to tune the portal caches and JVM.

• The limiting factor is not the absolute number of virtual portals, but the overall number of pages and URL mappings.

• In a limit and boundary test, the processor of the portal database machine was found to be the bottleneck.

• A large number of virtual portals can have an overall performance impact on administrative activities.

• Set up and administering a large number of virtual portals using the portal administration user interface can be time consuming.
