Automatically disable some features on large PRs

[fregante]

A few times people reported some features being slow on large PRs.

I wonder if, like GitHub does for large comparison, we could disable some/all features on large PRs and show a notice like "Some RG features were disabled because this page is gargantuan."

However, this need your help. Please post links to such large PRs. No real-life examples, no chances of this being fixed.

Is #1783 large enough?

Not for me, it's buttery smooth on my 2013 laptop. We need the users who report slowdowns to post their slow URLs.

With RH can barley get past the first file without chopping up. This is on a solid desktop computer.

Without RH freezes bus it moves. Moves but took 30 second to load the page.

Is my 2013 mac suddenly a super computer? That page also loads without a hitch. It does flash white for ~300ms but that happens even without RG.

That gif was recorded inside npm run start, so no other extensions running.

@fregante I should have recorded it... maybe next week

[fregante]

What's your CPU? Also try it in npm run start

It does lag a bit, but after a few seconds it's totally fine. I guess it's because GitHub folded most of the files so RGH doesn't really need to process a huge amount of lines. We probably need a PR that consists of lots of files that aren't long enough to be folded by GitHub.

@fregante maybe it was not a fair test. I did it on my work computer (in middle of work shhh). I did have about 45 (if not more) other chrome tabs open and work items too. I will test again next week with only that one page open and only RH enabled.

When I posted the link I incorrectly assumed that you would see the same results so I did not bother recording.

Closing. New issues can be opened with specific "feature + large PR" combination.
