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.

Spark Profiler
Spark can be used to see why your server or client is lagging.
Users can share a spark report via
/spark profiler start --timeout 300 which creates a report after 5 minutes. The spark report is useful in debugging why your server is lagging, so ideally you should always provide one while asking for support.

Create a spark report
/spark profiler start --timeout 300
that will output a link after 5 minutes
That CPU has not the greatest singlethreaded performance.
So it’s either your CPU not being able to handle your server as it’s so heavily modded, or you’ve just got a lot of entities that could be removed
The spark profiler will help
