            <title>[SERVER-57215] Use better data structure instead of deque for tasks in ServiceExecutorSynchronous</title>
                <link>https://jira.mongodb.org/browse/SERVER-57215</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;The ServiceExecutorSynchronous &lt;a href=&quot;https://github.com/mongodb/mongo/blob/2f4c2c6bdca301934d32a9f3a1f6fc76946f7b11/src/mongo/transport/service_executor_synchronous.cpp#L61&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;uses a deque&lt;/a&gt; for its queue of tasks. This means that every 4k bytes-worth of insertions we&apos;ll need to allocate another 4k bytes. This is unnecessary since that queue should usually be very small (and maybe max size of 1?) so we&apos;d be better off with a circular buffer or possibly some other data structure. I&apos;d be interested to see whether changing that helped with performance and if so making the change.&lt;/p&gt;</description>
