Portlets remain in memory for as long as they are configured to. The part that could be optimized is the creation of the transient portlet sets (and now wrappers) with every request.... A portlet instance is the runtime view of a portlet with its set of configuration and customization attributes. This runtime pair (the portlet object and attributes - from the psml page and configuration) define an instance. > -----Original Message----- > From: Wimmer, Matthias [mailto:matthias.wimmer@scr.siemens.com] > Sent: Tuesday, August 06, 2002 8:41 AM > To: 'Jetspeed Developers List' > Subject: Portlet Instances > > > Hello, > > I am just figuring out the difference between "Portlet", > "Concrete Portlet", > "Concrete Portlet Instance" and "User Portlet Instance".
