Is this an nntp server, or some other backend? You mention newsgroups,
which sounds like nntp, but also neomutt, which sounds like mail. Not
that I'm going to have much of a solution for you, but I do feel like
nntp handles large groups without too much trouble. Even if it takes a
while, it shouldn't spin up your fans. If it's maildir, Gnus does
currently have trouble with large message stores, mostly because it is
building the header cache and that is very slow/is done inefficiently/is
plagued by gremlins.

Someone™ will get around to fixing that eventually, but for the time
being it is slow.
