            <title>[SERVER-33706] Remove warning message about Windows FS cache configuration</title>
                <link>https://jira.mongodb.org/browse/SERVER-33706</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;By default the Windows System File Cache is configured without any minimum or maximum limit. The cache is responsible for managing when to release memory, and this behaviour can be somewhat controlled through the use of hints for the Cache Manager.&lt;/p&gt;

&lt;p&gt;Prior to &lt;a href=&quot;https://jira.mongodb.org/browse/WT-2670&quot; title=&quot;Inefficient I/O when read full DB (poor readahead)&quot; class=&quot;issue-link&quot; data-issue-key=&quot;WT-2670&quot;&gt;&lt;del&gt;WT-2670&lt;/del&gt;&lt;/a&gt; being implemented, we used the &lt;a href=&quot;https://github.com/wiredtiger/wiredtiger/blob/mongodb-3.4.1/src/os_win/os_fs.c#L526&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;FILE_FLAG_RANDOM_ACCESS&lt;/a&gt; flag by default, which instructs the Cache Manager to keep mapped views of the file in memory as long as possible (until Memory Manager doesn&apos;t signal low memory condition).&lt;/p&gt;

&lt;p&gt;This had the effect of filling up the System File Cache without releasing memory, which resulted in some users enabling &lt;tt&gt;direct_io&lt;/tt&gt; in order to workaround the problem.&lt;/p&gt;

&lt;p&gt;Now that &lt;a href=&quot;https://jira.mongodb.org/browse/WT-2670&quot; title=&quot;Inefficient I/O when read full DB (poor readahead)&quot; class=&quot;issue-link&quot; data-issue-key=&quot;WT-2670&quot;&gt;&lt;del&gt;WT-2670&lt;/del&gt;&lt;/a&gt; has been implemented we no longer see the System File Cache being greedy, therefore the warning about setting a maximum limit seems moot.&lt;/p&gt;

&lt;p&gt;Can we investigate removing this warning as it does not appear to be required any more?&lt;/p&gt;

&lt;p&gt;Or perhaps the warning should only be displayed if WT is configured to pass the &lt;tt&gt;FILE_FLAG_RANDOM_ACCESS&lt;/tt&gt; flag to the Cache Manager, which occurs when the user indicates a random workload with the &lt;tt&gt;WT_FS_OPEN_ACCESS_RAND&lt;/tt&gt; WT configuration flag.&lt;/p&gt;</description>
