Possible optimizations for server holders

[Danyash]

Is it gonna work? I dont know, maybe not. Is it safe? Prorably.

sysctl:

vm.swappiness = 1
vm.max_map_count = 262144
vm.dirty_background_ratio = 5
vm.dirty_ratio = 10
vm.dirty_expire_centisecs = 2000
vm.dirty_writeback_centisecs = 500
net.core.rmem_default = 262144
net.core.wmem_default = 262144
net.core.rmem_max = 4194304
net.core.wmem_max = 1048576
net.core.netdev_max_backlog = 5000
net.core.default_qdisc = fq
net.ipv4.tcp_congestion_control = bbr

VintagestoryServer.runtimeconfig.json:

{
  "runtimeOptions": {
    "tfm": "net8.0",
    "framework": {
      "name": "Microsoft.NETCore.App",

      "System.Runtime.TieredPGO": true
    }
  }
}

server.sh:

export DOTNET_gcServer=1
export DOTNET_GCHighMemPercent=90
export DOTNET_TieredPGO=1
export DOTNET_TieredCompilation=1
export DOTNET_ReadyToRun=0

Custom, but can be used as reference:
