I'd like to hear more about performance issues in large apps. Some of the other virtual dom libraries, namely Mithril and Mercury do not have an equivalent to shouldComponentUpdate. I'm wondering how those perform in large apps.

First someone would have to build a large app with them...

  I'm sure someone's built something at least semi-large with React by now. Would love to hear about the performance at scale.

    I've built an entire SPA based on React (and Backbone), which I guess can be considered semi-large. Performance was not an issue throughout the project, even with complex components like data grids. The rendering is negligible next to things like acquiring data from the backend, that's where most of the optimization went (caching, loading resources upfront, etc). React just makes it a no-brainer.

  Uh... like Facebook and Instagram?

    I was referring to Mithril and Mercury. I work on a huge React app :)

      I want to know how React performs at scale as well. So mind sharing? Do you have to use shouldComponentUpdate a lot? Have you tried omitting it?
