Hi ,
I have a problem with VisualEditor when editing on the English Wikibooks. First , it is too slow to display text which I am typing. It shows it in a slow and slideshow speed. Looks like it's quite slow. And , on Task Manager , it shows that it is using one and only 1 full(utilizes 100% CPU for that) thread for this. It stays at full utilization when I'm typing and becomes very slow. I'm using Internet Explorer 11.
