            <title>[SERVER-40012] Drop collection becomes slow after system runs for few weeks</title>
                <link>https://jira.mongodb.org/browse/SERVER-40012</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Our system generates relatively large amount of DBs (few hundreds), keeps them for a while and drop the oldest when needed to create new ones.&lt;/p&gt;

&lt;p&gt;We see that after running for several weeks, the drop operation become slow and takes large amount of CPU.&lt;/p&gt;

&lt;p&gt;We do the DB Drop by dropping all collections first and then the DB itself. It seems that the collection drop becomes ~x3 times slower and so does the CPU consumption.&lt;/p&gt;

&lt;p&gt;Restarting mongod solves the problem (for the next few weeks).&lt;/p&gt;</description>

&lt;p&gt;Thanks for the report. From your description, it sounds like you are hitting &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-34713&quot; title=&quot;Progressively declining dropDatabase performance&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-34713&quot;&gt;&lt;del&gt;SERVER-34713&lt;/del&gt;&lt;/a&gt;. I would recommend upgrading to the latest version of MongoDB 3.6, currently 3.6.11, to take advantage of the fix.&lt;/p&gt;

&lt;p&gt;Kind regards,&lt;br/&gt;
Kelsey&lt;/p&gt;</comment>
