On the application-deploytment\yourapp\ there is a orionweb.xml file that is used by Orion to define data about how the server will work. There is an option that define on which folder the server will serialize the session. This way if a the server does down then when it is restarted it is able to load the sessions it had running. Is there a way to avoid this behavior. I mean, I think this is slowing down the overall performance and it is a feature that I do not need. Then I would like to remove this feature. Is this possible? I am working with orion 1.4.5 .
