            <title>[SERVER-21998] insert into capped with mmapv1 should be throttled (core_workloads_MMAPv1 failed with multiple node replSet)</title>
                <link>https://jira.mongodb.org/browse/SERVER-21998</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;ul class=&quot;alternate&quot; type=&quot;square&quot;&gt;
	&lt;li&gt;with workload to insert into capped collection with MMAPv1, the secondary could not keep up&lt;/li&gt;
	&lt;li&gt;the speed to drain oplog is slow with capped collection, this may cause performance test timeout for waiting for w:ALL (w:NUM_OF_NODES) write (2 hours)&lt;/li&gt;
	&lt;li&gt;the repro step is same as &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-21646&quot; title=&quot;Inserts and updates to replicated capped collections must be single threaded&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-21646&quot;&gt;&lt;del&gt;SERVER-21646&lt;/del&gt;&lt;/a&gt;, except test this with MMAPv1&lt;/li&gt;
	&lt;li&gt;this issue recently surfaced due to we added forceSyncOplog for some of the workload, thus triggered timeout.&lt;/li&gt;
&lt;/ul&gt;


&lt;p&gt;for comparison, after fix for  &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-21646&quot; title=&quot;Inserts and updates to replicated capped collections must be single threaded&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-21646&quot;&gt;&lt;del&gt;SERVER-21646&lt;/del&gt;&lt;/a&gt;, WR insert_capped operates at 12,230 ops, and MMAPv1 is doing 34,250 ops&lt;/p&gt;</description>
