I'm a hue PyCharm fan, but if this is true then vim and Sublime must be barely usable. Python, it's great at...but open a big JS file and it...will...take...forever...to do the JS syntax highlighting, if it ever finishes. CoffeeScript is even worse, and almost always crashes.

It's always a little weird, because I have no performance issues anywhere else in it, and it's got ~7GB of RAM it could use.

I use PyCharm every day and IntelliJ and I have never had this problem. Maybe it's a resource issue with your hardware though and your version of Java. I use the new versions that bundle OpenJDK on a newer Macbook Pro.
