            <title>[SERVER-17798] Possible performance regression using SSL</title>
                <link>https://jira.mongodb.org/browse/SERVER-17798</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Running an insert only workload on two identical machines shows an 18% performance hit with SSL enabled over an 11h run, as indicated by the number of bytes written and the number of inserts reported by the client.&lt;/p&gt;

&lt;p&gt;There&apos;s also a 17% increase in the number of private bytes and a small but consistent 5% increase in user time CPU for the SSL enabled version.&lt;/p&gt;

&lt;p&gt;The tests are done on the same physical machine in 2 hyper-V VMs with the client on a third Ubuntu VM, so network is not the bottleneck. All the VMs are also on different physical hard drives.&lt;/p&gt;

&lt;p&gt;detailed windows performance counters and some basic analysis are attached in the excel spreadsheet.&lt;/p&gt;</description>
                <environment>Windows 2012 R2 in a hyper-V VM, 2 vCPU, 4GB ram, 128GB HDD. host machine is Intel i7 4970k, 32GB ram, 4 physical hard drives.</environment>

                            <customfieldvalue>&lt;p&gt;hammer.mongo insert workload, but may need to run for a few hours to let the insert performance stabilize, the initial difference may be up to 40% and they gradually converge. &lt;/p&gt;

&lt;p&gt;Also it&apos;s best to set the CPU affinity to 1 or 2 cores if running on AWS, otherwise network would be the bottleneck:&lt;/p&gt;

&lt;p&gt;mkdir hammer&lt;br/&gt;
cd hammer&lt;br/&gt;
wget --no-check-certificate &lt;a href=&quot;https://raw.githubusercontent.com/rzh/hammer.mongo/master/scripts/bootstrap.sh&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;https://raw.githubusercontent.com/rzh/hammer.mongo/master/scripts/bootstrap.sh&lt;/a&gt; -O - | bash&lt;br/&gt;
it will download everything you need.. to run insert traffic.. just edit simple_insert.sh and change HT_SERVER_URL to the location of the server&lt;/p&gt;</customfieldvalue>
