It is possible to reference the same object through multiple session attributes. I often do this to allow shorthand access to heavily nested properties.
Your method would count multiple references to the same object multiple times. An alternative approach would be to look at the amount of memory used by your application running with 200 users, then destroy 100 sessions and force grabage collection (or wait for it to happen). The difference in memory usage would tell you how much memory 100 sessions actually needed. Paul > -----Original Message----- > From: Khalid K.
