Performance Tuning for Visualforce Pages

Performance is an important aspect of mobile Visualforce pages. Visualforce has a caching mechanism to help you tune the performance of your pages.

To enable caching for a page, use this statement:

<apex:page cache="true" expires="600">
The parameters for page caching are:
Attribute Description
cache Boolean value that specifies whether the browser should cache the page. If not specified, defaults to false.
expires Integer value that specifies the period of cache in seconds.
