Server Performance Issues
-
Mostly just copying what I posted here already in the T4 section as a reply - it may be T5 as well or all of Plutonium - https://forum.plutonium.pw/post/172629
Our Plutonium gameservers have been a mess in the CPU performance department since the last two updates. Starting with the one that mentions memory improvements (r5304) and now the latest (r5314).
30 day CPU utilization average
3 month CPU utilization average
What used to be around ~20% usage with five T4 gameservers (ZM) and four T5 gameservers (ZM), is now averaging almost double with tons of spikes in the graph.

Any Staff or server devs can comment on this? I'm surprised no other server owners have commented on this issue besides one. Maybe others do not update or monitor their server's resource usage? It must be the case, since the only other post is someone running on under-powered hardware to notice the lag. Their VPS neighbors on that host are probably not happy with the CPU spikes and hammering. https://forum.plutonium.pw/topic/44919/performance-optimization
Here is a new chart with the 30d metrics. It has not gotten any better. Thanks in advance.

I have not seen anything like this since the update on my 42 servers (half bo1 and half bo2)... my CPU% holds steady between 15 and 16% 24/7.
I doubt others have either, hence the lack of other server owners commenting.

I have you confirmed it's plutonium using those resources and not something else?

Thanks for verifying. I will see if it's something on my end. I guess I over focused on the fact it started happening right as the update came where they mentioned memory/performance improvements.

no problem!
I'll keep a closer eye out as well to see if anything changes and let you know!

Changing the Windows VM CPU type from "x86-64-v3" to "host" in Proxmox fixed the performance issue. I have a theory that the Plutonium "memory usage improvements" update introduced overhead for emulated CPU instructions. I am not 100% since Plutonium code is a black box, but it makes sense.
This is probably why the other user in the linked thread running a "Digital Ocean Droplet" is experiencing issues as well. DO must use a standardized set of CPU instructions on their VPS so they can cluster and migrate VMs across hosts. Though even KVM with near-native execution would have issues on the lower end hardware (1 vCPU, 2GB RAM).

EternalllZM so... glad that fixed it for you, but i use x86-64-v3
so it is likely something else as well... -
