As I wrote on the review, I ran a vanilla Minecraft server for likely a week or so. The performance was great, the server was maxed at 5 slots and with 5 players there wasn't much lag, everything was fine. When I start a minecraft server I use a script to generate large portion of the map so during gameplay there isn't much of world generation.

Regarding your idea about modded version... it is a nice idea but I think that performance can only get worse. The Minecraft server is developed in a single-thread mode, I mean, the process doesn't use the multi-thread capabilities. So 2 vCore or 4vCore doesn't matter... what makes the difference is the raw strength of the single core.

I will give a try on modded server when I have time

Yeah that is true, Minecraft still doesn't utilize much except the first core, but since the processor's single core performance was not that bad, I still wanted to see how well it would perform.

I think you can try a lightly modded server, e.g. FTB Infinity, I think the server would have a hard time running heavy modpacks like RLCraft though
