VSCode is generally considered to be the canonical example of an Electron app well optimized. They have put a significant amount of work (much moreso than your average company producing an Electron app) into making it very responsive.

And it's still significantly slower than something like Emacs or Sublime (or, dare I say, IntelliJ?). I like, and use, Visual Studio code but it's hardly performant.
