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.

We do not support KCauldron here you will have to find their site.

It also occurs with vanilla Forge. I edited the post to say so.

Logs proving it then.

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

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

I was hoping for a way to profile what was actually using the CPU. Sorry for my misunderstanding of "vanilla", I meant that Forge itself was unmodified.

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.
