Hello, eyeryone
I checked the es single node load through cerebor and found that the load is very high, but the cpu utilization rate is very low. Why?
ES is deployed through docker, version: 6.8

kibana:

Sorry, I missed that you're under Docker. You probably need to look at [docker stat](https://docs.docker.com/engine/reference/commandline/stats/)s instead.

`docker stats`:
Load is still very high now
I am not sure if it is related to deployment in docker

I think docker stats are "outside looking in", so low CPU usage probably reflects low demand for cpu.
I don't recognize where you are getting the load stat, but if it is from INSIDE the container, I'd question it's validity. If you don't have performance problems, don't worry about it.
