Web Essentials for VS2013 Update 3 is extremely laggy

I have updated VS2013 to Update 3 along with Web Essentials. This is my only extension. Now when I run the solution, it hangs for ~ 3 seconds every ~ 5 seconds, making VS completely unusable when I debug. I cannot edit any source. Is anyone else experiencing this find a fix? My only solution is to remove WE.
