DH Server getting 10fps after Client-only was getting 120fps
I'm running a 1.20.1 server. First run was my client only. I ran around for several minutes rendering and generating LODs for chunks all around my world. FPS was stable at roughly 100fps-120fps. Had a friend join and everything worked fine. FPS was doing great at 100+fps for him.
I installed DH on the server so that everyone could share LODs and get real-time updates and as soon as I am loading in my FPS is a solid 10fps, and he is getting around 20fps-30fps (probably only because he is running at a lower resolution is my guess.).
Mod List:
- Distant Horizons
- Concurrent Chunk Management
- Faster Random
- FerriteCore
- Indium
- Iris
- Lithium
- Memory Leak Fix
- Mod Menu
- ModernFix
- Noisium
- Sodium
- Starlight

I'm just wondering how to fix the sudden frame drop. Am I missing something? Should we just run client-only? I don't know what to do. All help is appreciated.

Does this happen with DH as the only mod on the server and clients?
The mod list I am using comes as a pack so I haven't tried just DH on client and server. This modpack is otherwise the only thing on either side, client or server.
I will be the first to admit that I am absolutely brand new to modding Minecraft. Should I just remove everything except the exact same version of DH on the server-side?
I'll try that next.
