I have no patience for that.
I just open KUN in a new tab.
My i-pad runs slow too.
Try closing all of the tabs that you aren't using.
Pinch the screen to display all of the open tabs.
X out of the ones you're not using.
Also double click on the big on/off button on the side of the screen to display other open tabs, like games you might have been playing.
X out of them as well.
Go to settings
Scroll down to safari on the left, click it
Then scroll down to Clear History and Website Data, click it.
This sometimes helps to speed things up.
