            <title>[SERVER-24983] Remove method really slow</title>
                <link>https://jira.mongodb.org/browse/SERVER-24983</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;My application was running fine since jun/27, and yesterday the remove() method became really slow&lt;/p&gt;

&lt;p&gt;I&apos;m using an i2.8xlarge in AWS&lt;/p&gt;

&lt;p&gt;I tried to shutdown the service (db.stepDown() followed by db.shutdownServer()), and after 50 minutes it didn&apos;t shut down, I had to kill -9 &amp;lt;PID&amp;gt; to stop the process and reopen it, after restarting the service, the problem disappeared&lt;/p&gt;

&lt;p&gt;I can provide the diagnotics folder and db.currentOp() output when the slowness was happening&lt;/p&gt;</description>

                            <comment id="1320731" author="thomas.schubert" created="Mon, 11 Jul 2016 21:41:57 +0000"  >&lt;p&gt;Hi &lt;a href=&quot;https://jira.mongodb.org/secure/ViewProfile.jspa?name=ricardo_fanatee&quot; class=&quot;user-hover&quot; rel=&quot;ricardo_fanatee&quot;&gt;ricardo_fanatee&lt;/a&gt;,&lt;/p&gt;

&lt;p&gt;I&apos;ve looked over the diagnostic.data you have provided. I see that the bytes currently in your WiredTiger slowly increased. At around 2016-07-10 23:58:00 the WiredTiger cache reached 95% utilization and application threads began evicting pages and your performance degraded.&lt;/p&gt;

&lt;p&gt;MongoDB 3.2.8 contains a fix that significantly improves performance when the WiredTiger cache is full. Therefore, I would strongly recommend upgrading when it is released. Please see &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-24580&quot; title=&quot;Improve performance when WiredTiger cache is full&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-24580&quot;&gt;&lt;del&gt;SERVER-24580&lt;/del&gt;&lt;/a&gt; for additional details.&lt;/p&gt;

&lt;p&gt;Please note that a release candidate, 3.2.8-rc1, for MongoDB 3.2.8 containing the fix for this issue is available for download now if you would like to see if it addresses your issue.&lt;/p&gt;

&lt;p&gt;Kind regards,&lt;br/&gt;

&lt;p&gt;Thanks for reporting this behavior. I&apos;ve created a &lt;a href=&quot;https://10gen-httpsupload.s3.amazonaws.com/upload_forms/6c7ea8f4-a38f-492d-8eda-ae1728f3e4a9.html&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;secure upload portal&lt;/a&gt; for you to use to upload the files so we can continue to investigate. Would you please provide the logs as well so we can correlate the metrics in the diagnostic.data to the events recorded in the log?&lt;/p&gt;

&lt;p&gt;Kind regards,&lt;br/&gt;
