            <title>[SERVER-3380] log writing should be fadvise&apos;d</title>
                <link>https://jira.mongodb.org/browse/SERVER-3380</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;the log writing should be fadvised as &quot;don&apos;t cache for long&quot; as we typically don&apos;t go back and read it.  if the log were gigantic, this will push db data out of the filesystem cache if the data is touched infrequently.&lt;/p&gt;

&lt;p&gt;the same would apply to other files that output big files we don&apos;t need &amp;#8211; not sure what those are &amp;#8211; mongodump?  mongoexport?  i guess most temp files we generate we quickly use so probably doesn&apos;t make sense there.&lt;/p&gt;</description>
