That's what happens when the whole company uses high-end macbooks and nobody has an older PC. It's been noted thousands of times on HN but these US companies make money head over fist and do not give a single damn about people on "lower" end devices.

Large GitHub PRs are miserably slow even with a maxed out Mac Studio on gigabit fiber with single-digit ms ping to their server. It’s not an example of something that works well on high-end hardware but scales down poorly.
