We have finished a wine web magazine.

It consist of articles published once per week, it has one banner (via iframe) on the top that can changes, the nodes (that never change), a block on the right side that changes one per 2 or 3 days.

All the users are anonymous except one or two journalist who creates new pages.

The content don't allow being commented by users.

In this point, we are thinking to cache the entirely page, and to refresh it when it's necesary.

Is there, any idea, any module, any concept to acomplish it?

Is enough with the performance tab to reduce the traffic and to increase the velocity?

Please, answer!

Thanks in advance and excuse my english!
