            <title>[SERVER-81065] Cache the hash of the client metadata to speed up query stats computation</title>
                <link>https://jira.mongodb.org/browse/SERVER-81065</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;For some of our smallest/quickest queries the client metadata is actually a big portion of the query stats store key, and we recompute the hash on every query to detect whether we&apos;ve seen it before. The Client object lives as long as the client connection, so we should only need to compute this hash once per Client - which should be a lot more performant.&lt;/p&gt;</description>
