I'm not convinced of the performance, I heard my fans spin up when I first opened the new Github.com redesign a few weeks back and remember commenting on it to our developers ("how we destroyed your browsers performance" as a joke).

It's still a heavy thing to add to any page IMO. Which shouldn't be downplayed.

But it is very neat and I still like it.

Performance != resource usage in this case.

They optimized for hitting 60fps without any concern for the resources they were using as long as it fit in that budget

I agree that using this amount of resources in the browsers of visitors shouldn't be taken lightly (they could be on battery for example).

That's a good point which I didn't consider when I read the top end of the blog post.
