I used a 100KB json file from my Firefox profile

I missed that bit, so I should add that global-so-long-mode doesn't
care about text-mode by default. It mostly targets programming modes
(.json filenames included), but you can customize so-long-target-modes
to include text-mode if you think you're likely to encounter such
files in text-mode in practice.
However I wouldn't expect a 100K file in text-mode to cause anything
remotely like the degree of performance issue you've encountered. I
have a 256K single-line .txt file which suffers perceivable slow-downs
at the end of the file (in text-mode with visual-line-mode enabled),
but nothing remotely so catastrophic as you're reporting. On my
machine, I'd estimate less than a half-second delay when scrolling,
so the difference is several orders of magnitude.
Are you seeing that starting from "emacs -Q" ?
