I've rented out a dedicated server to have more control over my server(s).
It has a Xeon E-2236 (6-Core 3.4 ghz), 64GB RAM. I have 1 server running at the moment.
I'd like to add more servers to the group.  Would I be alright running 1 server per core?
Would 1 core be strong enough to handle a low-medium pop, lightly modded server?
If not i might consider upgrading to a 12-core Ryzen 5900X?? 🤤
Any advice appreciated!

I believe Unity will still only use 2 cores max, with Rust itself potentially using more for some things.

You should assign at least 2 cores per server.

Thanks ! So now I have a decision to make.
