            <title>[SERVER-65929] Unexpected profiling overhead when classical agg runs over SBE find</title>
                <link>https://jira.mongodb.org/browse/SERVER-65929</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Even with database profiling &lt;em&gt;disabled&lt;/em&gt;, Linux perf profiles still show ScopedTimer and BackgroundThreadClockSource as considerable contributors (depending on the benchmark, their share might be as high as 10%).&lt;/p&gt;

&lt;p&gt;Note: I noticed this when running $lookup benchmarks but the issue might be affecting other types of pipelines as well.&lt;/p&gt;</description>
