OS Name/Version: Ubuntu Server 25.04
Product Name/Version: AMP Release “Phobos”
v2.6.2.2
Problem Description: I recently bought a 10-year-old server with 92 GB of DDR3 Ram and 2 Intel Xeon X5650s (2.67GHz). I also have everything connect to an HDD so that could also be causing the slow down. I tried running a very intensive Crazy Craft Updated modpack (https://www.curseforge.com/minecraft/modpacks/crazy-craft-updated). Whenever I start it up it will stay on until someone joins and then it waits for 60 seconds before saying that there have been no ticks in 60 seconds and the server then restarts.

Steps to reproduce:
- Start the server
- Have someone join
- Wait till restart
Actions taken to resolve so far: Dropping simulation distance, dropping view distance, and limiting ram to 16GB to not stress the CPU’s. I have a feeling this is just an issue of the CPU clock-speed and that I may need to upgrade them soon, but I just wanted to see if there was something else I could be doing first.
