unraid Unraid Minecraft server specs?

[Shimoura Kinji]

Hello there.

 

I have an unraid server that is basically purely used to run plex and dumb storage. For that it works fine just fine since that doesn't require anything fancy.

 

My specs:

Ryzen 3 2200G

Gigabyte GA-A320M-S2H AMD A320

8GB G.Skill Value DDR4-2133 CL15 Single-slot

bunch of wd reds 8tb

Samsung 1TB ssd cache

 

I tried to run a minecraft server for me and my friends. We were 3 but max would be around 5. As long we did move as a group the server held up quite good. But as we moved separately the server lagged and finally crashed. I obviously did not build the server to be able to handle a game server but i wonder what i would need todo to do that. I read some server specs that were meant to run game servers but they always were build to handle much more than what i would want. I cant really get useful information out of them.

 

I have 2 questions. What made the minecraft server lag and what would i need to upgrade to handle game servers? my goal is mainly one minecraft server for my friends and i but it would be nice to know what is needed to maybe run more.

 

Since the problem was with us moving separately I thought it maybe was the ram i allocated to the minecraft server. Increasing it did change anything which leads me to beleave the cpu is the main factor?!

 

I would be rly thankful for any help you can give me

Loaded Chunks. A chunk is a 16x16x16 area, you can view chunk borders if im wrong.

16GB RAM, the CPU is fine, Minecraft servers don't need much CPU power

Have you tried running the server using Paper Spigot instead of vanilla? How about decreasing the server's view distance in your server.properties?

Do i need all 16GB for minecraft or just overall 16gb to give minecraft a big chunk of it?

Allocate 12GB to Minecraft and 4GB for the System, what OS?

Don't allocate too much ram to your Minecraft server. Less ram = better performance in java. If the heap is too big java has to search all it memory it had allocated to find dead objects

 

12 GB heap on a Minecraft server is too much. Especially for the OP use case. 2 - 4 GB is more than enough.
