Pull request page become so slow when pr is big

[namse]

My company used to make a big PR for major update. It's very difficult to review or check comment with code in Pull request page because it become too laggy to review in page.

I hope it become optimized.

I've been using the Github Pull Requests extension to get around this at the moment. With a relatively large feature pull request (~50 files touched), starting a comment causes the whole page to become unresponsive. With the extension, it seems to be a lot smoother.

Same here on Chrome. Switching to Firefox, and it's no longer an issue.

Here's my tampermonkey script to remind me to use firefox instead.

This has gotten incredibly bad.

Above 50 files changed the UI becomes unusable. How about paging the results instead of loading more than the browser can handle?

Indeed, it is horribly slow

[nbolton]

What browser?

[royathan]

It's rough in Chrome (massive slowdowns) it's unusable in Safari (can't modify PR description text).

It's reproducible by opening a PR in a go project that vendors the dependencies, you'll get a massive million line pr.

It is so bad, can't believe a company at GitHub's level is doing this

[nbolton]

What browser?

Commenting to get more traction on this. Using Chrome - PRs aren't even that big (~50-80 files, not too many lines per file) and slowness becomes unbearable. It really does sound like paging could help ?

Here's a few projects that may shed some light, in case it's react rerenders.

I saw some magic using this:
