----------------------------------

             Summary: Document vm.swappiness and mlockall in RefGuide
                 Key: SOLR-10306
                 URL: https://issues.apache.org/jira/browse/SOLR-10306
             Project: Solr
          Issue Type: Task
      Security Level: Public (Default Security Level. Issues are Public)
          Components: documentation
            Reporter: Jan Høydahl
            Priority: Minor


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?
