Rust server Linux usage

Hello Community,

i'm new to Rust Dedicated Server hosting. I'm familar with most other servers but yesterday i setup my first rust server with oxide on it.

The install and first run was very successfull and it runs like a charm. But... when i look for resource usage it´s a complete disaster! It takes 50% of my CPU-Power and this with no players on it. What the hell?

I know i have a big map (6000) but such a high usage with no load, jesus. Sadly when this can't be improved, i have to takedown rust on my list :/

What do i have to do? Is it very common that it runs so badly on linux? Are the devs working on a native linux version?

Who is hosting big servers on linux and can give some information?

My Hardware:
CPU: 6700k @4Ghz
RAM: 64GB DDR4 2133
OS: Debian 8
MISC: Runs in a docker container

 

(Just as the information)
CPU: 6700k @4.4Ghz
Windows 10
6k-map fresh server with few plugins CPU Usage: 14%
I think Unity more friendly with Windows

 

Is your CPU Usage per thread?
I recreate a new 6000 Size World and bind the container to one core (thread), now i have 42% Usage with no players.
That makes an overall CPU Usage about 5%, i think thats what Windows 10 tells you in taskmanager.
I only have 4 Plugins so this could be the difference to your 14%

After a few tests and corebinding the container it´s overall not that bad as i first thought. It confuses me in the first place that it consume so much idle usage, but i already read that this is normal. How much usage will approximately adds every player to the cpu usage? When i can host with the leftover ~50% around 100 player then its okay when only 10, its not. For now i have 63000 Entitys after 250000 it becomes critical or?

Thank you for your replies
