Even on the demo page[0], there's noticeable lag when typing. I have to delete the vast majority of the content for it to feel about as responsive as Google Docs, which still feels far slower than Sublime Text or anything native.

For reference, I'm on a 2012 rMBP with a 2.3 Ghz (turbos up to 3 Ghz when I'm typing) quad core i7.

I am a maintainer for Slate (the Editor framework this project is based on). I haven't looked at the code for this project but the most likely cause for the speed is the live HTML code view on the right. It might even be rendering and syntax highlighting the preview on every keystroke.

I use Slate and have many of the same features and some additional ones and it is more responsive so if you use this project in your code, you may not see the lag since you probably wouldn't have a live HTML view.
