            <title>[GODRIVER-862] critical performance downgrade while using goroutine</title>
                <link>https://jira.mongodb.org/browse/GODRIVER-862</link>
                <project id="14289" key="GODRIVER">Go Driver</project>
                    <description>&lt;p&gt;I have post this question to google groups, please lookup at: &lt;a href=&quot;https://groups.google.com/forum/#!topic/mongodb-go-driver/NwDvu18faG0&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;https://groups.google.com/forum/#!topic/mongodb-go-driver/NwDvu18faG0&lt;/a&gt;&lt;/p&gt;
&lt;ol&gt;
	&lt;li&gt;the latency increasing while more goroutine are used(from 1 to 8)&lt;/li&gt;
	&lt;li&gt;while I use mongo-cxx-driver to run the test, the latency is stable and low&lt;/li&gt;
	&lt;li&gt;while I use mgo, the latency increases too, but the latency is much lower than mongo-go-driver&lt;/li&gt;
&lt;/ol&gt;
