Scope of virtual portals

HCL 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, you 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.
  • Setting up and administering a large number of virtual portals by using the portal administration user interface can be time consuming.
