Hi Admincraft peeps! I've been running Vanilla+ Minecraft servers for years for my friend group, but in the last few months we've dipped into heavier mods, and the server performance is suffering, with a lot of crashes. Our current server is a custom Cobblemon + Create modpack. We have about 5 of us regularly, and I was thinking to make the server public as well, but I'd need to solve the performance issues first obviously.
In terms of the crashing, if anyone wants to take a look, here's the latest crash log. From my naive look, it seems that Distant Horizons is causing the server to hang, as ticks eventually just end up taking too long. One of my friends mentioned that the server started this frequent crashing after they went to the Nether.
Full list of server mods
Here's the breakdown with what I know I need to change:
Server specs:
Performance mods:
Here's my current plans to improve the server soon:
Any tips on improving my current setup would be much appreciated. I could also move to a better AM4 CPU like the 5800X3D or whatever is better. I know Minecraft mostly cares about single-threaded performance in this context, and the CPU is great in 2026. While I can afford to upgrade the server to AM5, it'd be very expensive as I'd need new RAM as well lol, so that's my last option.

Here's the breakdown with what I know I need to change:
Server specs:
- TrueNAS Scale (Debian-based, MC server runs in a docker container)
- AMD Ryzen 3700X 8 Core CPU
- 32 GB DDDR4 3200Mhz ECC RAM
- 4 CPUS, 16GB are allocated to MC
- Data is stored on HDD (I'll be moving that to an SSD)
- Minecraft is v1.21.1 w/ Neoforge as the modloader
Performance mods:
- BadOptimizations
- Lithium
- Flerovium
- Noisium
- ImmediatelyFast
- Concurrent Chunk Management Engine
- ModernFix
- Ferrite Core
- PacketFixer
Here's my current plans to improve the server soon:
- HDD --> SSD
- Chunk Pregeneration (10k radius perhaps?)
- I may just have to disable Distant Horizons
