Managed to Unmanaged

[Werkrat]

We're currently getting things ready to change from managed to unmanaged Windows.

How are you currently managing multiple servers on a single managed machine? Virtualization? Containers? Everything just thrown into different directories?

I'm curious, because we have overall cpu usage at <25%, while 1 server is using 200+%. What are you guys using to set resource limits?

Unless this is some proprietary information... Just trying to have similar performance after the switch.

Managed machines don't use any type of virtualization, all servers have full access to the bare hardware. We use a strict permissions setup to separate each server instance, each in new directories on the machine, each running under different user accounts. Resources are not hard-limited for each server process, they are only monitored and restarts / server stops are performed for servers going over the soft limits we set.

CPU usage graphs per server are normalized, where 100% usage is equal to 1 full logical CPU core of usage. This makes it easy to tell at a glance how many cores are being utilized overall for a server without having to divide by total core count of the system. Most game server software uses either 1 or 2 cores, few are truly multi-threaded.

Awesome, thanks for this info!

You will notice a performance boost when you go to a full machine. There is a bit of virtualization overhead that you don't have with a full machine. You literally have full use of all the resources at your disposal.
