As I said, I can only make you aware of the problems that comes with hosting a LUNI server. The code base is very unstable and broken, there are a ton of vulnerabilities that could be easily exploited and lead to even bigger harm.

That being said, the last version I hosted peaked at 2GB RAM with only around 10 players on it within 10 minutes. It is certainly not a good experience for players if you have to restart the server application every 10 minutes causing them to disconnect.

I’d rather wait until someone fixes these severe bugs (pointing a finger at @Xiphoseer ‘s direction here) before hosting a public server again.

In addition to that the server has some design issues that lead to pretty high bandwidths and CPU spikes. I’d recommend getting a full root server and not a virtual server for hosting purposes as well as unlimited bandwidth plans.
