Madhu, Are you trying to give access to implement sheet level security or document level security? You want to restrict the user to see only a barchart in the dashboard? The performance tuning can be done in several ways. It depends on your dashboard, environment. Performance can be tuned at design level, script level and server level. There are many documents available in our resource library for performance tuning and blogs too.

you may create a section access that restrict for certain user   ex. user 1 only dashboard he/she can see and in other user can see all sheets....
