Server CPU usage constantly at 200% with a sub-1MS ticktime, no one online

I run a custom modpack server with Forge 1558. The modpack is brand new and hasn't been heavily tested. However, the server is ALWAYS using 200% of my CPU (100% on both cores) on my Linux server, even when no one is online. The total ticktime in all worlds combined is always less than 5 ms.

 

Nothing else is running on the server. The CPU measurement was taken with the top command.

 

I took a NPS profile of the server with Sampler for about 20 minutes and this was the result; https://www.dropbox.com/s/fktby7l9fy7m10t/main.nps?dl=0

 

Even with no one on the server, CPU usage is at 200%. My CPU does not support downclocking, it remains at a constant 4.2 GHz speed. Temperatures are around 60-64 max. (If the CPU downclocked to say, 1GHz, that might explain the CPU usage, but not the temps!)

 

Is anyone able to interpret the NPS I provided? Thank you!

 

Edit: If it makes a difference, even with 7 players online the TPS remains around 18 or higher. The CPU is quite capable.

Thats nowhere near vanilla Forge. You have quite a few mods installed.

I'd start by removing the ones listed as coremods.

I do Forge for free, however the servers to run it arn't free, so anything is appreciated.

Well there are plenty of java profilers out there, visualvm comes with the JDK, JProfiler is also a good one, has a free trial IIRC.

      1.20.1; horrendous lag, latest log filled with "Saving chunks for level 'ServerLevel'" for every dimension

      By gsanders4319 · Posted

      I cannot find any information on why this is specifically happening in any of the logs and i'm getting annoyed. it manifests primarily as lag when breaking and placing blocks, or picking up items. Items will be picked up than disappear, only to appear in my inventory many seconds later, blocks will not place for over 30 seconds at a time. observable shows 100459 μs/t on minecraft:player spark profile doesnt seem to show anything strange as far as i can tell though except for that about 20% of the usage is something called crusty_chunks and another 20% is distant horizons, even when i have distant rendering disabled. I've attached the latest.log, spark profile and observable exports.
