For example, for the Core package: https://ocaml.org/p/core/v0.17.1
I am seeing between 615MB and 850MB of memory usage in Chrome on Windows: 137.0.7151.56 (Official Build) (64-bit) (cohort: Stable).
On a smaller package like odoc (https://ocaml.org/p/odoc/latest), I'm currently also seeing 627MB usage.
