Have been running the server for about a day, when it suddenly startede to decrease the server fps from around 100 to 20-30. The server has 16gb of ram and only has 3 players on a 4000 vanilla world. So i checked htop and it's still only using around 5.5-6.5 gb of ram, but the cpu cores are using between 60-100% instead of the 20-60% they did before. Anyone got an idea why this is happening? Was going to install oxide, but then this all happend out of the blue. 

it could be your plugins or entities, can you send us `serverinfo`, `plugins` and install Object Remover and run `objtop 100` to show amount of entities?

I don't have oxide installed yet, as this happend before I was going to install it, so I got nervous that it would mess it up even more, but looking under server info in RustAdmin tells me an EntityCount of around 80.000

Don't know if that helps or not.

then what if its just your cpu? what is it

6 cores from an epyc amd with 2.8 GHz

whats the model more specifically? lol, it can be quite good and some are way too bad. anyways 2.8 ghz sounds kinda bad if its boost, or what speed is this?

the 2.8 gHz is the boost

It seems like my server is choking it self

2.8 boost is really really low then, get a better CPU. amount of cores doesnt matter, single thread performance does.

misticos said it all, get a better machine.
