            <title>[DOCS-9586] Docs for SERVER-13345: Provide an option to disable journal compression</title>
                <link>https://jira.mongodb.org/browse/DOCS-9586</link>
                <project id="10380" key="DOCS">Documentation</project>
                    <description>&lt;p&gt;Engineering Ticket Description:&lt;/p&gt;

&lt;p&gt;I get better throughput for some workloads after disabling journal compression. At least one other JIRA was already open for perf problems with this &amp;#8211; &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-9802&quot; title=&quot;Single-threaded journal compression becomes a bottleneck when using &amp;quot;durable&amp;quot; writes&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-9802&quot;&gt;&lt;del&gt;SERVER-9802&lt;/del&gt;&lt;/a&gt;. &lt;/p&gt;

&lt;p&gt;My request is for a configuration option to disable it. If that is not feasible then the current code should be more clever about hiding latency from compression, like starting to compress earlier rather than in Journal::journal.&lt;/p&gt;

&lt;p&gt;From other testing I see that MongoDB writes much more to the journal than InnoDB writes to its redo log so making MongoDB less verbose will also help. See &lt;a href=&quot;http://smalldatum.blogspot.com/2014/03/redo-logs-in-mongodb-and-innodb.html&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;http://smalldatum.blogspot.com/2014/03/redo-logs-in-mongodb-and-innodb.html&lt;/a&gt;&lt;/p&gt;</description>
