I have developed a test application for my company using the RadDocking. I am noticing dramatically different floating DockPane performance between IE and Chrome/Firefox. I can fluidly drag the DockPane around in IE, but in Chrome and Firefox, there is unacceptable lag and choppiness. I can see this same behavior, to a lesser extent, on http://demos.telerik.com/silverlight/#Docking/FirstLook
Silverlight Version: 4.0.50917.0
IE Version: 8.0.7600.16385
Chrome Version: 8.0.552.237
Firefox Version: 3.6.10
Is it reasonable to expect vastly different performance of Silverlight across browsers? [An interesting side note; in BubbleMark (with 16 balls - http://bubblemark.com/sl3/TestPage.html
), I get ~185 fps in IE and FF, yet ~280 fps in Chrome.] Any suggestions for mitigating this issue?
