Hello, how much ram can a oneblock server with 20 users occupy?
Since you are not loading many chunks and most of your world is air I'd say with 8-12 GB you are good to go - obviously depending on how many plugins you are using and how they impact your performance.
Also check out the startup parameters to use the garbage collector.
That's way overkill...
This depends on many factors (optimisation, cpu, plugins, internet speed, etc.) but I would say 6Gb should do the trick.
20 oncurrent players would mean that he is pretty likely to expand this number to somewhat like 25-30. Depending on the plugins and other factors you would definitely need 8 at least.
If hes asking for 20 its probably for a community of 20 players (private server with friends or something) If he wants to expand of course hell need to add more in the long term
I just know with 1.8-1.12 you can likely do it with 3 GB Ram just fine. I'd do some experimenting and start with 3 GB Ram for newer versions as well.
Make sure to use Aikars GC (Garbage Collection) flags: https://mcflags.emc.gs
The dedicated to bentobox oneblock server we run with 12 plugins and bentobox on top, 25 ish players average in the weekend, we have it on 4gb and spigot. 1.16.5 - no issues so far.
2-3 GB Paper and good jvm flags
You're telling me that a 20 player one block server needs as much RAM as a 300 player factions server? No way in hell.
Show me one server that loads many chunks with several plugins on 300+ players with less than 12gb of ram^^
You clearly didn't pick up what I put down.
A 20 player one-block server, doesn't need 8-12GB of RAM. It barely needs 4. You've over-shot the margin of how much RAM is required to do these things.
In-fact, a 1.16.5 event server with over 300 players online loading about as many chunks as a 20 player, one-block minigame server only used 6.
Edit: It was actually a 300 player server.
