Minecraft chunk generation is notoriously though, and even a few players generating new chunks will bring the TPS down to an unplayable state very fast.
I know this isn't the point of Folia's test, but: > During the period when 1,000 players were online, we reached a maximum of ~7.9GB/s heap allocation and our GC was hovering around 2-3GB/s when averaged over a minute. As someone who dealt with soft-realtime telephony stuff, this makes me want to scream in horror. It seems like the platform really hurts the performance here.

The world is not static though. Each player loads in a lot of living entities (monsters/animals/...) and block entities (furnaces, redstone, ...) that all need to update. There's some overlap of course, though in a game like Minecraft where there's a near infinite world to explore that overlap is smaller than you would think.
While very impressive, something to note: >The server was prepared with a 100k x 100k block pre-generated world. Our custom plugin distributed new players to the least-occupied region.

And that's knowing a big part of the chunk generation already happens off the main thread.
Interesting to see how they scale a multiplayer big world. Not many systems try to do this. Improbable, Minecraft, Second Life, and Roblox are the ones I know about. Almost everybody else shards. Any other examples of really big shared seamless multiplayer worlds?

This is true to an extent, yes. Chunk generation can be real tough. That said, chunk generation has been re-written in Paper, so it's substantially faster than vanilla Minecraft.
When we did a large scale real player test on a much earlier build of Folia we had ~327 players at peak and we did not generate chunks because we specifically wanted to see how it ran. We didn't max out at ~327, we just didn't have more joins than that.
The project improved a bunch already so that number without chunk generation is very doable to beat if you didn't pre-gen any chunks.
Generally it's free performance to pre-gen your world though. Highly recommended for regular players.
On a side note, I've been trying to figure out how to write Java mods for server-side vanilla Minecraft server, but there is basically no documentation at all. Is it safe to say that this isn't possible? Which flavor of minecraft server is the best documented to write mods for, Spigot?
There are three competing standards right now: - Fabric (and Quilt), which uses a mixins system, a really flexible modding API that can do client and server modification - Paper (and Purpur, Pufferfish, Folia), which is similar to the old-school Bukkit/Spigot ecosystem and supports an intuitive API for server-side plugins. If you're aiming for >30 concurrent players you really need the sorts of performance patching t…
Fabric has quite a few performance mods that can achieve the same thing. I launched my new 1.20 map last week, and TPS was hanging on at 40 players without most of them even enabled.

There's a bit of a distinction in the Minecraft world between "mods" and "plugins". Even though to the outside perspective they're the same thing, the terms are used for two different communities/ecosystems, basically. "Plugins" are for bukkit-based compatible servers, like Spigot and Paper (and Folia, with some modifications). "Mods" are more for forge, sponge, etc servers. So you can kinda pick which direction you…
Are any of these choices restricted in their existing or likely future compatibility with where Microsoft is taking the game? My understanding is server admins will spend money on mods / plugins. Are there any server types more likely to garner paid license or plugins?
People do buy plugins but the vast majority of the plugins you'd want to use are free open source plugins. A lot of the paid/closed source stuff is kinda crappy or misleading anyway.
You can run a great server using free plugins and software. It might not be a money maker, but if your goal is to have people play and have fun and not buy stuff it's super easy and doable.
People do still donate to projects to support the authors who make the wheels spin.

Ultima Online, Star Wars Galaxies, and Planetside
Ultima Online is sharded. Biggest shard is ATL, with maybe 150 players.[1] Planetside 2 got up to 2000 or so, and may hold the record for a seamless land world MMO. [1] https://www.reddit.com/r/ultimaonline/comments/tr1r6j/uo_atl...

The Minecraft Java version is notorious for thrashing memory. It allocates and discards objects at an incredible rate, even when the player isn't doing anything. The server has a GUI where you can watch the memory allocation with its distinctive sawtooth pattern.
