Steps to reproduce
I have created a small sample which simulates the behavior: http://codepen.io/foxylion/pen/MKaxNN
Just drag the red container around and try it afterwards while pressing a key. After a few seconds the dragging gets noticeable slower.
When dragging a element while pressing a key that should not interfer with the preformance at all.

Thank you for providing this information. This issue appears to arise due to keyboard messages causing less coalescing of mouse move messages (namely when you have a key pressed down, we get a lot more messages). The general performance of jquery $.html is being investigated, so we expect this performance will be improved in our next release.
