Thanks for putting this writeup together! I use Elixir and Erlang every day at work, and the Discord blog has been incredibly useful in terms of pointing me towards the right tooling when I run into a weird performance bottleneck.

FastGlobal in particular looks like it nicely solves a problem I've manually had to work around in the past. I'll probably be pulling that into our codebase soon.

Note that Erlang 20 may have solved the problem that FastGlobal tries to fix (that of not copying large amounts of data unnecessarily)

Erlang 20 fixes the case where you're copying a constant literal, but unfortunately won't help if you're sharing a dynamically generated, but infrequently modified, term; like Discord does in this post.
