Modded Ubuntu Server: Constantly 500-700 ticks behind.

Disclaimer: I am illiterate with Java and Linux. Also, it is heavily modded with Medieval Minecraft 4 with forge.

So I built a 24/7 server with an ssd (I don't feel like checking, but it is more than big and fast enough), i5-6500, and 32 GB SODIMM at 3200. It runs on ubuntu, because Debian gave me a lot of problems and once again I am illiterate.

Installed server pack directly and it has been working, that's for sure. I only keep the server script running at any time and backup/reset every couple days on. Issue is those ticks. considering the specs of the mini server I built, it should not be 500-600 ticks behind with only one (or no) player. Roughly 700-1500 with two players.

Anyone willing to help, and sorta explain the logic, I would greatly appreciate it. Remember, I am less than a novice with Linux and java.

MINECRAFT_VERSION=1.20.1
