Oh, I open it up about once a week. It&#x27;s not that much slower than, say, Sublime Text, <i>without any plugins installed</i>. However, I like to load up my text editors with IDE-like affordances. I also wanted to experiment with a bunch of Facebook languages so I thought I&#x27;d try Nuclide, which basically made Atom unusable that last time I tested it.<p>It&#x27;s a shame that it doesn&#x27;t work better, because it&#x27;s truly a great idea. I have some faith that the performance will improve but there is a limit and I&#x27;m almost certain that that limit is below that of editors that render natively. Now, if they started supporting a statically typed JS like TypeScript or if they did something like restrict the plugin architecture to a simpler DSL and the theming language to be a smaller subset of HTML, that might improve things, but it would also no longer &quot;just work&quot; for web developers wanting to write plugins for it.<p>Edit: Also if WebAssembly becomes a widespread thing it would help performance greatly.
