That's surprising. I used IntelliJ today after a pause and found it unbearably slow. For instance, scrolling a ~6 page source file lags so much it's extremely irritating.

It's also fantastically bloated. There's so much stuff I have to disable to make it barely usable. And most of the supposedly helpful lightbulbs suggest changes that make absolutely no sense.

I can absolutely believe that IntelliJ has its fans because it has a ton of features, but for me it's just unusable.
