> I think we should document sane best practice OS level settings in the ref 
> guide, e.g. in 
> https://cwiki.apache.org/confluence/display/solr/Taking+Solr+to+Production
> Such as lower system swappiness or ability to use mlockall (like this ES page 
> https://www.elastic.co/guide/en/elasticsearch/guide/current/heap-sizing.html)
> I also found this github repo https://github.com/LucidWorks/mlockall-agent - 
> it is old, did anyone have good experience with the agent for locking Solr's 
> memory?
