If the first link refers to

1: https://emacs.stackexchange.com/questions/34342/is-there-any-downside-to-setting-gc-cons-threshold-very-high-and-collecting-ga

then

(setq gc-cons-threshold (eval-when-compile (* 1024 1024 1024)))
(run-with-idle-timer 2 t (lambda () (garbage-collect)))

obviously means that this author does GC as soon as Emacs is idle.

Not to me.
