I know this thread is getting a little old but just in case this helps someone else...
I also have this issue and I can definitely put it down to Web Essentials in my case. But, more specifically, Web Essentials once I open up a .less or .css file in the IDE.

I have restarted the IDE and the usage goes back to normal but again as soon as I open a css file the CPU starts to climb then the whole IDE becomes unusably slow. Closing all less/css files does seem to bring the CPU/IDE back to earth eventually.

My 2 workarounds so far:

1. Uninstall WE    :-(
2. Edit my .less and .css in Notepad++ and use the IDE for everything else

Neither is a particularly great solution!

This is with VS2013 Pro + Update 2 and the latest release build of WE. Next step is to see if VS update 3 RC + latest nightly build of WE has the same problem.

Edit: A thought has just occurred. I have only recently had to change from VS Premium to VS Pro and I don't recall the problem happening with the Premium version. I wonder if it is just the Pro version??
