            <title>[SERVER-82056] Investigate and fix slow bulkWrite addition of insert replies.</title>
                <link>https://jira.mongodb.org/browse/SERVER-82056</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;The &lt;tt&gt;addInsertReplies&lt;/tt&gt; method &lt;a href=&quot;https://github.com/mongodb/mongo/blob/8569377425b4da5b520590d84d164c3211465e9b/src/mongo/db/commands/bulk_write.cpp#L166&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;here&lt;/a&gt; takes about 2% of the total time that the bulkWrite thread spends.&lt;/p&gt;

&lt;p&gt;In a patch in which I commented out this method, along with populateCursorReplies, I saw a significant performance raise. &lt;/p&gt;

&lt;p&gt;See &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-76662&quot; title=&quot;bulkWrite perf testing against vectorized inserts&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-76662&quot;&gt;&lt;del&gt;SERVER-76662&lt;/del&gt;&lt;/a&gt; for flame graphs.&lt;/p&gt;</description>
