It depends on the application.

Do you have some apps that are inactive for long periods of time, and “wake up?” Better to do it at the highest level. That gives the OS power and o essentially shunt whole VMs away and give the active ones full power.

Are they all pretty active all the time? Are memory performance requirements not too high? Is latency a priority? Best to do it inside, I suppose.

EDIT: For what it’s worth, I found that no zram is best in some scenarios. Sometimes applications just barely, rarely scrape the memory limit, and if I enable a big chunk of zram they scrape it more frequently, then don’t give it up and keep active pages in zram. Rare swapping to an ssd ended up much, much faster.

I agreed with the title, but then downvoted immediately upon reading your post.

Censorship is not Reddit’s problem. It’s enshittification.

Reddit didn’t fail because Spez has some niche political opinions he pushes and you aren’t allowed to say, it failed because its algorithm/UI is structured to farm users and turn to shit.

Lemmy has major problems and power tripping mods, but its existential issue (IMO) is collapse from spam, trolls, attention algorithms, commercialization, and so on.

But federation is a good first step to avoiding the enshittification traps, like the original internet did until Google/Facebook got such a grip on it.
