ASP.NET AJAX Download Performance Improvement Request
Date Published: 15 April 2008
I’m a big fan of ASP.NET AJAX in general, but one concern I have and something that has forced me to use other technologies is the size of the library. It’s about 85kb when compressed and unfortunately that is quite large if you’re trying to include it on most every page on a site (or, much much worse, every advertisement in a large Microsoft developer advertising network). One can certainly argue that this will be cached, and that is true, but for many sites that get most of their traffic from search engines (ASPAlliance gets over 70% of its traffic from this), you have to assume that many users will not have the .js file cached, and that is a significant increase in the total page size.
