Hi Chuck, First of all thanks for your answer.
The application isn't mine, so I can only guess as to how much memory a session is occupying. The SESSIONS.ser file is occupying 112kb, I suppose it should be occupying more or less the same in memory. But that is only an assumption, correct me if I'm wrong. If so, then it would be less likely that the sessions are causing GC's and thus slow down the application. Referring to your comment whether my question is in the spirit of what André posted before, I'm not completely sure whether that is the case. I was not asking for something to be solved, I was wondering whether it would be possible that many idle sessions slow down an application. You're reply answered my question perfectly: It could be possible. >From that point, I can continue investigating, and maybe later post a new question regarding that matter with all the information I figured out, in case I'm stuck. Thanks again.
