Cpu performance

[eparini]

Hello,
I'm trying to optimize cpu performance using pivotviewer. During my test (with IE 11) I found an odd behaviour: the demo at pivot.lobsterpot.com.au/html5.htm on idle the cpu load is 0% or a bit more, but with my example or with this example (http://linkeddata.uriburner.com/HtmlPivotViewer/?url=http%3A%2F%2Flinkeddata.uriburner.com%2Fpivot_collections%2Fcollection_2014-06-27_15-47-17.719287.cxml%23%24view%24%3D1) the Cpu load is around 40% because it's calling the AnimateTiles function constantly.
Is it the expected behaviour? What do you think?
Thank you in advance

Emanuele

I noticed it in Firefox too which is about the only reason why I can't use this great plugin in a production environment right now.
