Make source code (text) editor faster
With a lot of extensions installed, the source code editor can really slow down on some older systems. Scrolling isn't smooth, and typed text can have big delays in showing up.

It slows down on brand new systems as well. I'm seeing all kinds of keyboard lag, especially when using navigation keys. That said, I think this is pretty much covered here: http://visualstudio.uservoice.com/forums/131389-visual-studio-performance/suggestions/2204073-make-editing-typing-scrolling-more-responsive-
