Ask HN: Has GitHub's web UI gotten tremendously slow or is it just me?

1 SirensOfTitan 2 8/22/2025, 7:32:33 PM

Sometime since March or so this year, GitHub has become utterly agonizing to use. Particularly:

- The file explorer drops frames, scrolling and searching cause lockups.

- Reviewing anything but the most trivially small PRs doesn't work: clicking on files often lazily loads them and never finishes, ctrl+f causes huge frame drops

I've tried both the new and old PR view and neither is particularly good on either Safari Technical Preview or Google Chrome, and my general purpose machine is an M1 Max with 64 GB of RAM.

Welcome to responsive design!

It's pretty slow yes. It's one of the worst RAM eaters and has been feeling very sluggish for a long time.
