Use Caching to improve the performance of your application

OutputCaching enables your page to be cached for specific duration and can be made invalid based on various parameters that can be specified. The Cache exists for the duration you specify and until that time, the requests do not go to the server and are served from the Cache.

Do not assign cached items a short expiration. Items that expire quickly cause unnecessary turnover in the cache and frequently cause more work for cleanup code and the garbage collector. In case you have static as well as dynamic sections of your page, try to use Partial Caching (Fragment Caching) by breaking up your page into user controls and specify Caching for only those Controls which are more-or-less static.
