Application Module Release Mode

Hi sirs;
I'm just starting a new struts based application and adf uix + bc4j;
What i was wondering is;
If we will have a improve of performance, releasing more times the application module in stateless mode; like the following;
All data forms (form related to data) will have an <<exit>> button and all the others links should be disabled. this exit button should command the form's dataforward action to release the application module in stateless mode;
This exit button also will redirect the user to the main menu page;
So, when the user get in an "data form", all struts ,toy stories based actions, will have the complete life cycle and will release the application module in stateful mode.
One event called onExit marks the release mode to stateless to it's life cycle.
what are your opinion about this approach ?
Thanks
