            <title>[DOCS-15348] [Server] Unclear reference to lagging majority commit point in PSA</title>
                <link>https://jira.mongodb.org/browse/DOCS-15348</link>
                <project id="10380" key="DOCS">Documentation</project>
                    <description>&lt;p&gt;The page &lt;a href=&quot;https://www.mongodb.com/docs/manual/tutorial/mitigate-psa-performance-issues/#overview&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;Mitigate Performance Issues with PSA Replica Set&lt;/a&gt; stated:&lt;/p&gt;
&lt;blockquote&gt;&lt;p&gt;If one data-bearing node goes down, the other node becomes the primary. Writes with w:1 continue to succeed in this state but writes with write concern &quot;majority&quot; cannot succeed and the commit point starts to lag. If your PSA replica set contains a lagged secondary and your replica set requires two nodes to majority commit a change, your commit point also lags.&lt;/p&gt;&lt;/blockquote&gt;
&lt;p&gt;It&apos;s unclear to what situation &quot;and the commit point starts to lag&quot; refers to. Does it mean BOTH: &quot;If one data-bearing node goes down&quot;, AND &quot;writes with write concern &quot;majority&quot; cannot succeed&quot;? Or does it ONLY refer to &quot;writes with write concern &quot;majority&quot;&quot;?&lt;/p&gt;

&lt;p&gt;In other words, does the lagging majority commit point in a degraded PSA can be mitigated by not using w:majority, or is it unavoidable as long as the secondary is down?&lt;/p&gt;

&lt;p&gt;This is specific to MongoDB 5.0, where we cannot disable read majority anymore.&lt;/p&gt;</description>
