            <title>[SERVER-49966] Examine performance bottlenecking of VersionAPI ServerStatus Metrics</title>
                <link>https://jira.mongodb.org/browse/SERVER-49966</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;As part of changes in &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-49379&quot; title=&quot;Metrics for Versioned API&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-49379&quot;&gt;&lt;del&gt;SERVER-49379&lt;/del&gt;&lt;/a&gt;, we acquire a mutex in every instance of execCommandDatabase in service_entry_point_common.cpp and runCommand in strategy.cpp &#160;(within the addTimestamp function of APIVersionMetrics that is invoked by APIVersionMetrics::update) We also acquire this same mutex in the run method of ServerStatus cmd (generateSection method of APIVersionMetrics).&lt;/p&gt;

&lt;p&gt;Examine the performance impact of &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-49379&quot; title=&quot;Metrics for Versioned API&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-49379&quot;&gt;&lt;del&gt;SERVER-49379&lt;/del&gt;&lt;/a&gt;.&#160;&lt;/p&gt;</description>

I ran &lt;tt&gt;sys-perf&lt;/tt&gt; patches with an increased workload for the &lt;tt&gt;InsertRemove&lt;/tt&gt; task for before and after the commits, and it seems like the performance was similar in both cases. Closing this ticket!&lt;/p&gt;</comment>

Now that metrics are merged, ask David Daly for advice. If API version metrics do cause performance issues, when and where would we expect to see them in our perf testing?&lt;/p&gt;</comment>
