@jakearchibald wrote a great article about the way githubs javascript lib (which is pjax) works and how it could be improved.

maybe this is something which could improve performance under the hood. just to let you know...

Thanks for letting us know! It's clever, but still a huge hack. We're definitely interesting in using some streaming technology once it's available in browsers.

There's another issue going on here (which I left out of the reduced example in my post). When I view https://github.com/w3c/ServiceWorker/issues/920 the HTML is 4.4mb when I'm logged in. I think it's because it includes the edit form along with every comment.
