Improve the performance of the XML (Text) Editor
The XML (Text) Editor can get very sluggish when editing a largre XML file (1MB or larger).

The XML file doesn't need to be big at all to show all kinds of keyboard lag; I see the same thing with even small files. That said, I think http://visualstudio.uservoice.com/forums/131389-visual-studio-performance/suggestions/2204073-make-editing-typing-scrolling-more-responsive- covers your concern.

I opened a 50MB XML file in the text editor and tried to delete an element. RAM usage went up to 2.6GB as devenv reformatted the document and then I got an unhandled exception.
Perhaps VS isn't designed to be able to edit a file that big, but it seems to indicate a problem which if fixed would benefit smaller files.
As a comparison, I opened the same file in Emurasoft EM Editor (www.emeditor.com) which used 11MB RAM and was instant!
