There are so many different ways you can optimize your website performance. You may think why we need to worry about website performance when internet connection speed is growing faster and faster.

Using a cookieless domains for static content will also improve performance, otherwise every time an image, css, or script file is requested all the cookies are sent in the request and the response.
To use cookieless domains, serve static content from a different subdomain (static.myawesomesite.com) and set your cookies for www.myawesomesite.com. In that way, requests to static.myawesomesite.com will not contain any cookies. If you use cookies heavily this can shave up to a couple kilobytes off of each request.

Sprites are one way to reduce the number of image downloads. There is a <asp:SpriteControl> which is available as part of NuGet to do this.
