Note that I use something similar, but just enlarging to something I
trust my system can handle:

;; Make startup faster by reducing the frequency of garbage
;; collection.  The default is 800 kilobytes.  Measured in bytes.
(setq gc-cons-threshold (* 100 1024 1024))


My system has a few tens of Gigabytes of memory, so running GC if it
finds that it consumes more than 100 MiB does not risk OOM. Algorithms
may depend on garbage collection being active to avoid unbounded memory
usage.

But it causes GC pauses to be much longer — that does not hurt during
init (I don’t interact with Emacs anyway), but it would hurt during
regular usage.

Therefore at the end of the init file this reverts to a more sensible
value for continuous operation:


;; Make gc pauses faster by decreasing the threshold again (from the increased initial).
(setq gc-cons-threshold (* 20 1024 1024))


Best wishes,
Arne
