Hi,

I am running multiple instances (4 data nodes) on the same machine.  
When running load tests, I see the each node CPU is ~20-30% and Host CPU is ~92%.

Elastic recommend to configure Node.processors in such case and it require additional configurations: [https://www.elastic.co/guide/en/elasticsearch/reference/current/modules-threadpool.html#node.processors](https://www.elastic.co/guide/en/elasticsearch/reference/current/modules-threadpool.html#node.processors)

What are the additional configurations?  
Will it improve the index rate?

Thanks...

What do you mean sorry? The docs page shows what you can configure.

The page mention: Note that this is an expert-level use case and there’s a lot more involved than just setting the `node.processors` setting as there are other considerations like changing the number of garbage collector threads, pinning processes to cores, and so on.

What doe it mean changing the number of garbage collector threads, pinning processes to cores, and so on?
