Sun Java System Portal Server 7.1 Deployment Planning Guide

Average Session Time

Average session time is the time between user login and logout averaged over a number of users. The length of the session time is inversely proportional to the number of logins occurring (that is, the longer the session duration, the fewer logins per second are generated against Portal Server for the same concurrent users base). Session time is the time between user login and user logout.

How the user uses Portal Server often affects average session time. For example, a user session involving interactive applications typically has a longer session time than a user session involving information only.
