Web page becomes extremely slow when create a new PR

[Bruc3Stark]

Description

After creating a new pull request, the website will become extremely slow when click button like "File Changed", etc, especially in some large repos. Sometimes, logging out and logging in again or changing a browser could probably help. Is their any way to accelerate the web page? Or what configuration might help to solve problem like this? Thanks a lot.

Is this still a problem since now there is a files pagination?

I am pretty sure there could be still some slow cases:

• Slow for the backend handler code (doing "git" operations)
• Slow for the network traffic, when the diff result is large
• Slow for the browser rendering, when the result generates a lot of HTML elements
• Slow for the browser JS (the DiffTree, etc)

Each case can be reproduced separately I guess.

But for this issue, it's not clear about which case it is for.

I think it's a duplicated of #14734
