            <title>[SERVER-57472] Yield service executor worker threads after sinking messages</title>
                <link>https://jira.mongodb.org/browse/SERVER-57472</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;As part of the rewrite to the ingress networking layer/SSM for the fixed-pool-project, service executor threads that formerly yielded after sinking a message to clients no longer do so. Sys-perf performance testing revealed this to negatively impact performance for write-throughput for workloads with many change-streams listeners, and further testing showed that re-introducing the yield significantly improved write throughput on those workloads. We should add this yield back in to resolve that regression. &lt;/p&gt;</description>
