1.28 Server Performance REALLY BAD
Need More Info, NormalPublic

Description

Dunno what changed with 1.28 but server performance has been seriously affected.
I've already turned off my other server on the box which helped earlier, fps jumped up to 70fps.
just got home and now it's back down to under 10fps

Ryzen 7 5800X running at 4.58GHz shouldn't be running this poor!

Hello Nate_LapT.
What are the server specs?
What is the maximum player count?
Any mods you are using?
Any modifications in your xml files?
Can you please upload your mission files and Storage?

This was on OVH at the time, running with an AMD Ryzen 7 5800X
The server was managed by Omega manager with an affinity of 12, there were multiple servers on the server, which had to be shutdown after the 1.28 update due to the performance issues.
I have access to the server for another week if more is needed from it.

Player Pop: 80

Bitterroot Mission files: btw, latest aren't up to date on github yet.

I've moved to a new host a few days ago and now running on Ryzen 9 7950X3D 16-Core Processor managed with Architect and we haven't seen the performance issue, though we also haven't had full pop since migrating.

The servers are not very comparable... Architect seems to manage affinity natively along with the new server being Ryzen 9 vs 7 and twice the cores...
I'll let you know if we still experience the same performance issues on the new hardware once the servers full pop later.

Both of the servers are Windows 2022 STD.

New host

@Nate_LapT you go back to your old server logs and find comparable time when the server population was matching your current peaks on the new server to compare "like with like"
Server performance dropped in 1.27 and again in 1.28. We shouldn't need modern day beast of servers to run DayZ.
https://community.bohemia.net/wiki/DayZ:Server_Requirements

@sileed Agreed, Even with my lower end server (a processor that came out in 2020) you'd think the performance would be much better.
My new server a Ryzen 9 with 10 servers, some with pop hasn't dipped yet, but we haven't hit full pop yet since the update.

I apparently am not logging the pop count... But these are times we had 80 pop with Queue, Queue ranged from 1-20 depending on the moment.

The Ryzen 7 5800X was hosting 3 DayZ servers, 1 of which had 0 pop and shutdown. Other server had very low pop.

What we observed on CFtools online feels as it was lower fps longer than what is logged in RTP
As we were seeing sub 20fps for longer than what appears in the RTP logs.

Maybe there were mods updating at 15:22:27.478, but I don't recall any servers restarting, and there was only 1 other server online at the time.

Since the update to version 1.28, we’ve been experiencing massive server FPS drops.
We haven’t added any new mods or made any other significant changes that could negatively impact server performance.

Before the update, on version 1.27, we had stable server FPS around 5k with 60 players connected, according to CFTools.

Since updating to 1.28, server FPS with the same player count has dropped drastically, now fluctuating between 5 and 20 FPS.

And we dont got bad Server Specs

We have also seen a major performance drop since 1.28. No mod changes either. We are also seeing a ton of stutters and I cannot figure out what the cause is.

Can vouch for this as well. No changes for us between 1.27 to 1.28 except the removal of a few mods, with a few thousand server FPS being lost

I've seen performance drop also on my Linux server, having active AI also eats a lot more performance than it did before 1.28.

This is what i was thinking it was. When our server is low in pop, maybe around 5 people, the FPS will be solid, 28k ish, but within a few minutes (at random) with the same amount of people on, and only a towns worth more of AI, the FPS drops all the way down to 19k, and seems to stay there. We are using a 7800x3d , 64gb, 1tb ssd system, with 1gig network

Before 1.28, during testing of our server before we opened, we had 10 testers on at once doing all kinds of things, we even stress tested the hardware spawning over 1000 AI across the map, and it held up better than it does now after 1.28

Similar but Different issue.
My experience with Linux and pop. Anything over 14 players tanked the FPS to basically 0
