            <title>[SERVER-83304] Investigate MSG_ZEROCOPY for large messages</title>
                <link>https://jira.mongodb.org/browse/SERVER-83304</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;In &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-81784&quot; title=&quot;Pass MSG_WAITALL to send/recv when doing sync networking&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-81784&quot;&gt;&lt;del&gt;SERVER-81784&lt;/del&gt;&lt;/a&gt;, Mathias suggested investigating MSG_ZEROCOPY along with MSG_WAITALL:&lt;/p&gt;

&lt;p&gt;Could also investigate using&#160;&lt;a href=&quot;https://www.kernel.org/doc/html/latest/networking/msg_zerocopy.html&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;MSG_ZEROCOPY&lt;/a&gt;&#160;with large messages to keep the&#160;&lt;tt&gt;Message&lt;/tt&gt; object alive until the kernel knows it won&apos;t need it while allowing the kernel to avoid doing its own copies. They claim it is only beneficial for messages &amp;gt;10KB.&lt;/p&gt;

&lt;p&gt;Splitting this into its own ticket because I think it warrants its own investigation (after looking at it for a bit, I think we would have to determine a threshold for message size at which it would be a useful flag to set)&lt;/p&gt;</description>
