I’d just like to interject for a moment. What you’re refering to as GNU + Linux, is in fact, Linux

Imo it would be awesome if every person could have only one single account. Bans and restrictions have much more impact which forces users to behave more like irl.

What about people who want to criticize their oppressive government without risk of being identified from their post history? People questioning their gender or sexuality who don’t want to come out to everyone yet? People who view or post NSFW things and don’t want it associated with their primary account?

There are plenty of valid reasons to have multiple accounts besides ban evasion.

Yes, hosting providers do run servers on desktop hardware. See for example Bisect’s dedicated server options which all have desktop Ryzen processors.

Smaller Minecraft servers can run just fine on standard server hardware, and I’m sure that’s what most hosting providers use for their lower tier server plans, since you can cram dozens of Minecraft servers onto one machine. But the main limitation for larger servers is single-threaded performance, which desktop CPUs are just far better at.

Very large servers generally use server software like Folia which multithreads the game (like 2b2t) or split the server into many smaller servers (like Hypixel), which eliminates the single threaded performance issue but has some serious drawbacks.

For small playercounts a server CPU works fine, but my server regularly has 20+ concurrent players and sometimes has up to 50 so we kinda need the performance.

A typical server unfortunately won’t work for my use case, as Minecraft servers are highly single threaded workloads and desktop CPUs are just far better than server CPUs in that regard.

What are you doing that mainly needs single threaded performance, running a Minecraft server?
