DayZ Server admins: Experience with two servers on one dedicated machine?

Recommended Posts

Hello - I am looking for help running two DayZ servers on one machine better. The second server is degrading the performance of the first one despite the machine's specifications being more than sufficient for running the two servers.

It is a dedicated machine running a Ryzen 5 3600X (ovh) with Windows Server 2019. It is setup using OmegaManager so we can run two instances. The server only has one server-side mod for tools but does have lots of buildings and is filled with player objects throughout Chernarus. We currently do not wipe, but that will change. I am not trying to make performance perfect until next wipe, just better. With 60 players, it averages around 500 FPS (server side tick rate) and low pop (-20) is 3000 or so. The CPU is at 15% load with max pop on the populated server. RAM, network, and hard disk are also fine. I know a wipe would probably resolve a lot of this, but I feel the issue is more with how the two servers interact due to very low load on the system.

When starting up a second server (Livonia) using OmegaManager, the first server immediately looses half to 2/3 of its server FPS. It will go from 500-400 down to 200-100 or even lower. As soon as the second DayZ instance is closed, the first server climbs back up in server FPS. I was able to reproduce this multiple times when the main server was at max population. Even just running the other server empty with no players was cutting performance on the full server in half. I am able to easily run both servers when the main server's population is low. It is only when the main server is full that the second one really hurts its performance. I do not understand why this is happening as per resmon.exe the CPU is less than 30% load, the RAM is less than 40%, and SSD and network are at less than 1% load on both.

Does anyone know if any optimization needs to be done to the config files or OmegaManager to get them to run well?
