I'm truly confused about the notion of JetBrains IDEs being slow. I'm using both IDEA and VSCode, for different projects but sometimes even concurrently (because IDEA's Dart plugin is somehow dumber than VSCode's but IDEA's database explorer is so useful) and if anything then VSCode is slower with autocompletes and refactorings. Typing speed has never been issue with either so I'm really curious what sort of hardware you're running JetBrains products so that they are slower.
Ya no idea, I've used JetBrains IDEs for years and they've been great. I suspect a lot of people have 400 chrome tabs open and then open up their IDE and blame their IDE for being slow.
