I'm running a server with a few of my friends. i've been having server lag as soon as we're loading in chunks with quite a lot of lag when we're 5 players on at the same time. i have tried giving the server 32Gbs of RAM in the server config but as far as i can tell using /spark it's only using a max of 7Gb.

While running the server it's only using max 22% of memory and about 10 to 20% CPU usage
could anyone tell me how to get some better performance?

Hmm... Seems it's entities, but that really isn't too many. So I'm going to assume it's the 2.6GHz processor...
You can try adding servercore. It will dynamically change mob caps and other settings when the tps gets bad.

Here is the config we use
Note you probably want to change the view distance setting in this as it's set to 10

It’s a dual cpu running a total of 48 threads so i’m not sure if the GHz should be much of a problem
I’ll see if the config works as soon as i get on my pc again but i’ll update once i do

Minecraft performs better based on single core performance. It is not that multihreaded. Its better than it used to be though.
Are you saying it's a dual core CPU??? That's ancient and not going to work well

Any way to up the allocated RAM since it’s stuck on 7GB?
clear bolt
Its not ram limited right now... The profile shows its only using 4GB

It’s two 12 Core CPUs as far as i remember

Oh, gotcha. Yeah not sure a dual core ever had 48 threads haha

As far as i can tell the Lag only really happens when we are exploring. The server keeps giving messages about overload running 40 ms to 300ms behind (400ms is the highest i have seen)
Even tho the server is really only using around 20% of it’s overall capacity when it’s lagging the most.
So i’ll try to run the config, see if it gets better. If not i’ll run another 60 sec /spark when it’s at it’s worst.

Huh. see I thought it was going to be world gen lag, but I didn't see that on the spark profile. If that's the case, you simply need to pregen the world, that way when you explore its just loading/unloading chunks instead of generating them on the fly. I assume we included Chunky like in AoF6, so look up the commands for that.

Yes, while generating chunks it cannot multithread that operation, every part of world gen has to happen in a specific order and has to be finished before the next chunk loads. You can also add C2ME mod which helps improve world gen speed. It previously has had issues with certain mods, but we are using it on our AoF7 server without issue
