CPU Affinity and Numa


(Morphers82) #1

I am hosting multiple nodes on single servers that include multiple numa nodes.

I would like to setup some kind of cpu/core affinity for each elasticsearch process and a better numa policy than the default.
I am on ubuntu 16.04.
I am hoping this will increase performance of indexing/search.

I can't find much documentation on this, especially specifically for elasticsearch.

I already set the number of processors in the yml file to the number of total available threads divided by the number of nodes on the server.

I think there has to be some setting i have to put into the jvm.options file for cpu affinity, just have no idea what it would be?
