-----------------------------------------
Assignee: Lorina Poland
> Add Operating System Specific Setup Documentation for Cassandra
> ---------------------------------------------------------------
>
> Key: CASSANDRA-14816
> URL: https://issues.apache.org/jira/browse/CASSANDRA-14816
> Project: Cassandra
> Issue Type: Improvement
> Components: Documentation/Website
> Reporter: Joey Lynch
> Assignee: Lorina Poland
> Priority: Low
>
> There are a number of operating system tunings that can vastly improve
> Cassandra's performance on Linux in particular things like:
> # Setting {{/sys/block/${DEVICE}/queue/read_ahead_kb}} to something more
> reasonable like 32
> # Setting the qdisc on modern linux to something better like {{tc-fq}} with
> {{bbr}}
> # Setting {{nofile}} ulimits properly and {{fs.file-max}}
> # Potentially raising {{vm.max_map_count}} even higher than the default
> debian package does
> # Using raid instead of jbod
> # Mounting /tmp on a tmpfs and turning back on {{PerfDisableSharedMem}}
> And many more ... I think many of the recommendations from [Amy
> Tobey's|https://tobert.github.io/pages/als-cassandra-21-tuning-guide.html]
> 2.1 guide may still be pretty relevant.
> Perhaps we can document some of these in the website's Operations section?
