Hi,
the project, in which I’m working, have a performance issue in IE, when the page is loading in IE11, it takes between 2.5-4.5 seconds, while in chrome it takes less than a second to load (firefox/Edge load in less than 2 seconds);  Resize is also a problem, but my main concern is Loading the pages… the master page has multiple nested splitters (rad panes), I debug it and server’s time is less than a second, using dynatrace, fiddler, and dev tools, I find that the time is related to the Resizing of panes…
(See images  https://screenshot.net/7o1dgcn  ,   https://screenshot.net/jd9qgud )
I’ve looked at multiple forums (both telerik’s and otanother sources) for similar problems, and optimizing tricks… I tried some of them, but the resizing is still the main issue...
I include a link to a video showing the problem http://screencast.com/t/LQNCaVFD (ie vs chrome) with a simple project, one with one single radsplitter (RadPanelSingleSplitter.aspx) the other one with multiple nested radsplitters (RadPanelNesting.aspx, which is similar to my project), the nesting page takes at least double the time to load, and also the more html I include, the more time it takes to render (resize)…

Has anyone else have similar issues?

Best Regards,
JC
