Hey,

im running a FTB Beyond Server on my dedicated Rootserver.

Rootserver Specs:
Debian 9
Java 8
12 Cores
32GB RAM

The Modpack is modified with Sponge and some Sponge Plugins.

I know that the main Java Part is running on only one core. I think thats the Problem.

The Server laggs with more than 10 Players (Usually 20 Players online).

I use the standard startscript with 28GB allocated RAM. I tried parameters like -XX:parallelGCThreads=20, but I think this isnt working.

Are 20 Players too much or what can i do to fix this laggs?
