I have been running YSlow against my site and the Microsoft Ajax files are quite hefty:
http://ajax.microsoft.com/ajax/3.5/MicrosoftAjax.js = 99.3k
and
http://ajax.microsoft.com/ajax/mvc/MicrosoftMvcAjax.js = 136.7k
开发者_开发技巧Is there likely to be a minified version of these files on the Microsoft CDN soon?
http://ajax.microsoft.com/ajax/3.5/MicrosoftAjax.js is already minified... if you look at the code.
the only way that its going to do better if they gzip them ... which they do for certain browsers...
http://ajax.microsoft.com/ajax/mvc/MicrosoftMvcAjax.js is coming up as a 404
http://ajax.microsoft.com/ajax/mvc/1.0/MicrosoftMvcAjax.js is the correct address and is minified as well...
I get that MVCAjax is 4.3 KB (when saved to disk) and MVCAjaxDebug is 12 KB ....
...I know you are looking for performance but I think this might be a dry well.

You can minify the files yourself here.
