Optimizing Your ASP.Net Pages for Faster Loading and Better Performance.

If you read the internet and all of the websites dedicated to Asp.Net you will inevitably read about the wonders of the DataGrid, DataList, and Repeater controls. While each of these has its place, if you are only displaying data there is a much faster and more efficient means to do so.

Let’s say you have a page that displays articles based on a query string. Take my article pages for instance. Each article is stored in a database and displayed on the page based on the unique id of the article as stored in the database.

A normal asp page execution procedure goes something like this. The code queries the database based on the Article I.D. and then brings back that information to the page where you display it in the fashion that you would like. This is a fairly straight forward approach with asp and is done all the time.

So how do we speed up our asp.net pages?

Number 1: Use Asp.Net Caching!

This is a no-brainer, and I won’t go into the brilliance or details of asp.net caching here because at the time of this writing Google has 2,780,000 articles on the topic. Basically instead of querying the database each time the page is loaded you only query the database once and load that result into the system cache. Subsequent calls to load the page retrieve the data from the cache as opposed to the database which gives you an instant and considerable performance boost. You can then set the cache for how long the cache should store the information as well as many other features. If you are not using the cache, you should be whenever possible!

Number 2: If possible, do NOT use the standard Asp.Net controls.

That’s right. The standard asp.net controls are designed for rapid development and not page performance. They allow you to design pages that grab and display data very quickly but their actual performance suffers because of the extra overhead which is there for ease and speed of development time and not page execution speed.
