IntelliJ 13 running very slow

Hi, I'm using IntelliJ IDEA 13.1.3.
It's running slow when i have a coffeescript file open of 1000+ lines. In the task manager (Windows 7), it's always at 15%+ CPU, the editor window is jerky. How can i find out what's taking the cycles?
My machine is decent:
Intel i7 2.2GHz 4 core, 8 thread
14 GB RAM
SSD

Hi Andrey, I've attached both the dump + the coffee file.

... now added a 2nd dump (while typing) - occured to be the first dump may not have run at the right time.

If I edit a js file of 32,000 lines the IDEA editor is unusably slow. I'm starting to use other editors for these larger files. Situation is becoming untenable, can we please get this sorted out.

Now the problem actual for both CoffeeScript and JavaScript files? Am I right?

if so please record full thread dump according to instruction https://intellij-support.jetbrains.com/entries/29983118-Reporting-performance-problems

(Stack dumps you attached before don't have enough information to sort out the problem)

Thank you.
