Very poor server performance on AMD Epyc.

    Hello!
    The dedicated server has some major performance issue's running on an AMD Epyc Rome 7282 CPU.
    It's running Windows Server 2019 Standard (EVAL) with 32GB RAM. It's a KVM VPS orchestrated by CentOS 8 (Altho the KVM doesn't matter because it's the same on a non-KVM'd Server 2019).
    I have replicated an exact configuration on two other servers running older Intel Xeon's and the issue is not present. The issue also replicates itself on the AMD regardless of world, settings and mods.

    Server sim speed will tank randomly at periods, even on a fresh world and becomes unbearable to play whenever a ship is near, even on smaller ships. The server also loves to spew out connection problems.

    Is there a conflict between the newer Epyc Rome's or is the support for these CPU's just not there yet?

    Kind regards.

    The CPU speed is 2.8gHz according to AMD

    Space Engineers does better with CPUs that are faster and not so many cores.

    So a typical server is basically the wrong set-up for SE. A consumer rig with a very fast or even overclocked CPU above 4gHz or even hitting 5gHz on 4 cores is going to fair a LOT better.

    SE needs to be able to calculate and process a lot of data, not just route it.
