            <title>[SERVER-57305] Mongod&apos;s response is extremely slow</title>
                <link>https://jira.mongodb.org/browse/SERVER-57305</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;we have some 3.4 sharding cluster, sometimes a node will become&#160;&#160; extremely slow. it is very slower even if we are just conneting to the mongod process.&lt;/p&gt;

&lt;p&gt;Maybe our data is a little big , the&#160;avgObjSize of many collections are hundreds of KB , if is it the main cause of a poor&#160;performance?&lt;/p&gt;

&lt;p&gt;I have collect&#160; &#160;perf top data and pstack , hope that can help you analyze the problem.&lt;/p&gt;
