                <link>https://jira.mongodb.org/browse/SERVER-15990</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;The startup warnings relating to NUMA and hugepages configuration are specific to the mmapv1 storage engine. We should not issue them if we are using a storage engine other than mmapv1.&lt;/p&gt;</description>

                            <comment id="757849" author="charlie.page@10gen.com" created="Thu, 6 Nov 2014 16:25:45 +0000"  >&lt;p&gt;I&apos;d have to see testing, but I imagine microsharding along NUMA for heap would be hugely beneficial.  We 8 node boxes available for testing once we get stabilized.&lt;/p&gt;

&lt;p&gt;However, it is possible that storage engines are NUMA aware, so making this per storage engine is a good idea.  I&apos;m just not aware of any that like NUMA/THP.&lt;/p&gt;</comment>

&lt;p&gt;Wired tiger seems to disagree that these aren&apos;t important.  Is there some WT notification?&lt;/p&gt;</comment>
