Windows Server Stuttering and Low FPS visible in server console (Day 69, 6k Map)

[Thedarklurch]

Hi everyone, I'm reaching out here because I'm at a loss. We're on day 69 of the game and are currently having major issues. We keep experiencing micro-stuttering; the zombies don't move smoothly, and when we drive through the world, we repeatedly encounter lag that causes one of us to teleport around.

We have a dedicated server with a hosting provider.

It has the following specs:
Hardware Specs:

• CPU: AMD EPYC 7443P (4 vCores)
• RAM: 10 GB (currently using ~6.1 GB RSS)
• DISK Space: 17.7 / 20 GB
• Map: 6k World (Day 69)

The Problem (Evidence from Logs):

• Server FPS: Drops to 15 - 20 FPS during movement (visible in server console [Pterodactyl]), causing AI lag and rubberbanding. [Ingame we have 70 - 80 FPS]
• Heap Limit: The internal Unity Heap is capped at 3.5 GB (Max: 3530.3 MB), which is nearly full.
• Warning: WRN [Steam] Tick took exceptionally long: 44 ms.

While we're playing, the server shows the following usage on the dashboard:

CPU Usage: 65.54% / 400%
Memory Usage: 5.97 GiB / 10 GiB
Disk Usage: 17.49 GiB / 20 GiB

We're currently playing on version V2.6 (b14)

and have kept the default settings:

MaxZombies: 64
MaxAnimals: 50
ViewDistance: 12



Now my question is: is the server too underpowered for the game with these settings, or should we upgrade something? We’d like to finally have a smooth gaming experience again. Up until day 30, we hardly had any issues, but starting on day 35, we started having more problems. I’d appreciate any tips that could help me solve this problem.
