            <title>[SERVER-43768] Investigate the slowest sections of ReplSetTest data consistency checks and remove any wasted downtime</title>
                <link>https://jira.mongodb.org/browse/SERVER-43768</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Investigate the slowest parts of the consistency checks ReplSetTest.checkReplicatedDataHashes and ReplSetTest.checkOplogs to identify and remove any areas of wasted downtime. Wasted downtime would be any time spent not doing useful, required work. For example, waiting for data to propagate over the network or waiting for an arbitrary timeout to fire in the server e.g. a heartbeat interval or election timeout.&lt;/p&gt;</description>
