I am looking for a fast and lightweight UI framework to build a simple mobile web site. I have already tried jquery-mobile, but it is slow and it's too heavy for the kind of web site I wish to build. The average load time using jquery-mobile for my site is around 3s which is even higher on slower networks that uses a GPRS connection.
I used this web site to run a load time test http://mobitest.akamai.com/m/index.cgi
i think 3ms isn't slow at all!
But try Kendo UI from Telerik. It is really fast and you have huge possibilities, although it costs "a bit". If you use it professional it is great ;)
