title: How to determine as to how many sessions are too many for a web application
body: <p>I have Jboss application server running Oracle Commerce. I have 5 Page serving instance[VM Servers] and around 300 users browsing site at any given time. I am trying to come up with a number for Session timeout, so that customer have enough time to browse and checkout, but then also do not want too many open sessions that would hold up the memory. So my question is there a rule of thumb to determine the session timeouts?</p>
  
  <p>Jboss 7, Java 7 with 8gb memory for each jvm. Currently session timeout is set at 10 mins. Would like to increase it to 30 mins. </p>
