Performance and decreasing the footprint of JavaScript/CSS size of pages is very important for major websites. You all clearly know that as it was one of your goals with Lightweight rendering. We would like documentation that shows the approximate file sizes for the Javascript and CSS files per control. We would also like to know the base libraries: AnimationFramework.js - KB? PopupScripts.js - KB? TouchScrollExtender.js - KB? ScrollingScripts.js OData.js (why does this load if we aren't using OData?) OverlayScript.js NavigationScripts.js etc We would like more control over the loading of these and knowing what functionality dictates what scripts. This would really help us evaluate whether to use a control or look for a lighter jQuery alternative as we are very concerned with file sizes and the loading time of our web pages.
