CLion 2017.3.1 ranges ts performance

Just FYI,

There is quite the delay for some reason when using the ranges ts code in the IDE. Not a problem, just a minor annoyance.

Hi, Matt.

Sorry for the inconvenience! Could you please try enabling memory indicator (`Preferences | Appearance & Behavior | Appearance | Show memory indicator`) and keep an eye on it for some time? If it is close to the limit at the time when you are experiencing the problems, then try increasing the Xmx JVM option according to this guide. Does that help?
