Which of these techniques results in performance improvement of a web site?

Option 1 is wrong as Copy web site is for synchronization
ex: if changes are made in an assembly, they should
be updated to different users.

Option 2: Publish web site allows a web site to be pre-compiled which improves performance.

Option 3: Caching always stores data in a cache allowing the
user to retrieve data from cache instead of repeating
the full page cycle.
