I've had this issue running Oh My ZSH on a Chromebook several years ago reading git branch info. Running a leaner config than omzsh would likely have been better, but I decided to just fully switch to fish.
Why would slow storage affect "alt-tabbing between Firefox and terminal"?
I'm not sure he was remarking on that one but it is possible. FF uses a lot of disk cache. You'll find this out if you ever run out of space. Lots of random crashes that are hard to diagnose.
