Why does Visual Studio 2010 slow down when editing a large .js file?

Question

I have .js file that is currently over 4400 lines, editing it is very slow (about a second delay from keypress to character appearing in the document).

Are there any particular performance issues related to editing large file or JavaScript files?

N.B. I am using VS2010 SP1 and am running it with 16GB of RAM, and have installed http://jsoutlining.codeplex.com.

Answer 1

Disabling the JSOutlining extension has improved this.
