I'm pretty sure that I fed this back as part of the in-app feedback some months ago, but figured I would come and write on phabricator as well as this is still an issue.

The feature itself is rather neat, and quite a few diffs actually show something that should be reverted for me.
However, the experience is really quite bad, as loading diffs seems to take forever. (And I'm on rather fast internet)

I'm not sure what it is doing behind the scenes but it would be great if it could be sped up, and maybe even preload one future diff
