Not sure why the response got downvoted. I personally found Git performance to be, well, okay on macOS (but depends) and absolutely horrible on Windows due to very slow stat() calls on NTFS.
Of course, in a large enough monorepo Linux performance would also suffer, but to a much lesser degree.
Also, conveniently, both Windows and macOS have an API for recursive directory watch, whereas Linux doesn't (in Vanilla kernel). Inotify can only watch the immediate directory you're observing + there's a pretty low default limit on the number of inotify descriptors that you're allowed to have on top of that
