Holy crap, try bringing the Chromium codebase into CLion. UI freezes up constantly while the C++ indexing engine does... stuff. Then eventually hangs untill SIGKILLed. Even after giving the JVM 48 gigs on my 64gig dual Xeon 36 core workstation.

Which is a great argument for Xi's architectural choice to disentangle syntax highlighting and display out into separate processes.

A lot of people refer to atom and vscode when complaining about the performance of modern text editors and while they are not the only modern text editors by far, they are definitely some of the more popular ones at the moment.

I can definitely say that atom has performance issues. I get lockups and stutters working on small and medium sized files (hundreds to thousands of lines) and it is infuriating. It is unfortunate because there are a lot of great new plugins for these platforms but they consistently cause me all kinds of trouble.

Old school editors(like vim or emacs) or modern IDEs perform much better as text editors nowadays compared to plain modern text editors.

IntelliJ is still slow even when I throw 12 cores Xeons at it.

... aside from the fact that I can compile some projects faster than it takes just to start up.

If IntelliJ were a car, it'd be gas guzzling SUV with a hole in the gas tank.
