This is spot on for me as well. I always wondered how VSC was so much faster given that they are both on top of Electron. In either case, this is all great news.
Electron, iirc, is just the UI layer. Atom actually has a lot of code written to render, edit, and rerender text (they were initially using React at one layer of the process). I can't find it now, but there was a good blog post from the Atom team that discussed their efforts in detail. So I guess I'm trying to say that I believe the code handling the slow parts is predominantly unrelated to the UI layer. Also, iirc, VSCode's editor is based on Monaco (http://www.zdnet.com/article/microsofts-browser-based-dev-to...).
