Hi I was playing with http://examples.sencha.com/extjs/6.0...ard/#dashboard and it in chrome and IE 10 on desktop run fast, but when I try it on iphone 6 plus ,
ipad2, or mini-ipad3 the app run ok, but is not running smoothly, this app is ready or optimized to run on table and phone?

I would like to get feedback from other, paying with this example in table or phone
