You're comparing a text editor to an IDE. They're different classes of software. Sublime can't do 10% of what IDEA does - which is fine, they've got different use cases.

While I agree, Visual Studio doesn't lag when you're typing code or using IntelliSense.

Honestly, neither does IDEA, for me at least. I've heard it can be pokey on spinning disks, so maybe that's part of it.

I'm on a newish MacBook pro with an ssd, and it's hardly instant.
