Determine Your Tuning Goals
Before tuning you portal, work with portal system administrators and portal
developers to set the portal performance objectives based upon the projected
requirements of your portal. Objectives include the number of users, the number of
concurrent users at peak load time and their usage pattern in accessing Sun Java™
System Portal Server.
You need to determine these two factors:
• Are you tuning for portal applications rapid response?
• Are you tuning for a large number of user concurrency?
As the number of users concurrently connected to the portal increase, the
response time decreases given the same hardware and same set of parameters.
Hence, gather information about the level of usage expected on your Sun Java
System Portal Server, the anticipated number of concurrent users at any given
