                    <description>&lt;p&gt;The simplifier has a minimal overhead around 750 ns, which is noticeable for simple queries on small one index collections, such as the collections in YCSB.&lt;/p&gt;</description>

&lt;p&gt;Message: &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-82809&quot; title=&quot;Do not attempt to simplify trivially simple expressions.&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-82809&quot;&gt;&lt;del&gt;SERVER-82809&lt;/del&gt;&lt;/a&gt; Do not attempt to simplify trivially simple expressions&lt;/p&gt;

&lt;p&gt;The overhead of the simplifier becomes significant when processing high-throughput loads with very simple expressions.&lt;br/&gt;
