As the user hits will be more to the page. we cant keep it in a server. This will lead to performance issue.
OH REALLY! - from your vast experience with
servlets you have deduced this?
You have made actual measurements?
The experience of countless web sites using the sessions mechanism counts for nothing?
If this data (too large to keep on the server) has to be transmitted with every request, you think it will give better performance than having the server side grab an object from memory or from disk? Better do the numbers before you assert that.
