            <title>[SERVER-16415] mmapv1 replica multi collection insert is 70% slower vs no replication</title>
                <link>https://jira.mongodb.org/browse/SERVER-16415</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;it seems mmapv1 insert with multiple collections does not benefit from CLL&lt;/p&gt;

	&lt;li&gt;two insert function as in the attached js file, test is done with 20 thread insert into 20 collection or single collection,&lt;/li&gt;

&lt;ul class=&quot;alternate&quot; type=&quot;square&quot;&gt;
	&lt;li&gt;2.6.5 and master (with single collection) have around 24-26% impact when enable replica&lt;/li&gt;
	&lt;li&gt;master with multiple collections show 68-72% performance impact when enable replication&lt;/li&gt;
	&lt;li&gt;it seems master benefit a lot from multiple collection insert in standalone mode, while replica set doesn&apos;t.&lt;/li&gt;

                            <comment id="792713" author="schwerin" created="Mon, 22 Dec 2014 23:48:17 +0000"  >&lt;p&gt;For legacy writes, at least, the difference between the multi-collection and single-collection cases, the performance difference comes from contention on the MODE_X lock on the oplog collection.  In the single collection case, in what I believe is a representative run under vtune&apos;s concurrency analysis, we see 13.1% of time in _logOpRS, with around a third of that in the lock manager and ScopedTransaction.  In the multi-collection case, it&apos;s two thirds of the _logOpRS time, which is now itself 36.3% of runtime.&lt;/p&gt;

&lt;p&gt;repl::getNextOpTime and RCI::setMyLastOpTime have some contention in both cases, which indicates an avenue for improving the repl-vs-norepl performance.&lt;/p&gt;

&lt;p&gt;&lt;a href=&quot;https://jira.mongodb.org/secure/ViewProfile.jspa?name=rui.zhang&quot; class=&quot;user-hover&quot; rel=&quot;rui.zhang&quot;&gt;rui.zhang&lt;/a&gt;, can you run the multi-collection test against 2.6.5 and 2.8.0-rc3 with the change that each collection is in its own database?  New baselines for rc3 would also be nice.&lt;/p&gt;</comment>

Add a &quot;writeCmd&quot; true field to each benchRun op to do that: &lt;a href=&quot;https://github.com/mongodb/mongo/blob/master/jstests/noPassthroughWithMongod/benchrun_substitution.js#L6&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;https://github.com/mongodb/mongo/blob/master/jstests/noPassthroughWithMongod/benchrun_substitution.js#L6&lt;/a&gt;&lt;/p&gt;</comment>
