in RefGuide
[ https://issues.apache.org/jira/browse/SOLR-10306?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17036148#comment-17036148 ]
Jan Høydahl commented on SOLR-10306:
------------------------------------
Please see [GitHub Pull Request #1256|https://github.com/apache/lucene-solr/pull/1256] ([https://github.com/apache/lucene-solr/blob/solr10306-swappiness/solr/solr-ref-guide/src/taking-solr-to-production.adoc#avoid-swapping)] for a proposed new section in the Ref Guide. The text is inspired by this article [https://unix.stackexchange.com/questions/265713/how-to-configure-swappiness-in-linux-memory-management]

> Project: Solr
> Issue Type: Task
> Components: documentation
> Reporter: Jan Høydahl

> Remaining Estimate: 0h

> 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?
