            <title>[SERVER-69383] Improve performance of Decorations</title>
                <link>https://jira.mongodb.org/browse/SERVER-69383</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;(generated by SA onsite)&lt;br/&gt;
There may be places in the Decoration system that are inefficient in a significant way, particularly the Decorations on OperationContext which are created and destroyed very quickly.&lt;/p&gt;

&lt;p&gt;One idea was to elide the invocation of trivial destructor callbacks entirely. Instead of invoking a no-op function pointer, allow it to be nullptr and don&apos;t invoke anything.&lt;/p&gt;</description>
