too much switching time when switching mui:Link item which contains big datas

Nov 4, 2014 at 2:30 PM
hello.
I wonder why a usercontrol page, which contains large datas such as TreeView having 500 TreeViewItems, takes too much time when switching between mui:Links.

It takes time bout 5 seconds. It's a little boring.
Also, it takes same time whether swiching large datas page to other page or inversely.

Thanks for your help.
