            <title>[SERVER-49405] Ability to pass --fast flag to zstd</title>
                <link>https://jira.mongodb.org/browse/SERVER-49405</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;According to &lt;a href=&quot;https://github.com/facebook/zstd&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;https://github.com/facebook/zstd&lt;/a&gt;&#160;&lt;/p&gt;

&lt;p&gt;&quot;zstd 1.4.5 --fast=7 is much faster than snappy at same compression level.&#160; But right now, there is no way to tell mongodb to use zstd at --fast=7&quot;&lt;/p&gt;

&lt;p&gt;&#160;&lt;/p&gt;

&lt;p&gt;Noooo!!!&lt;/p&gt;

&lt;p&gt;Without --fast, Zstd is not as good as Snappy. With --fast it immediately becomes a no-brainer.&lt;/p&gt;

&lt;p&gt;Surely this is doable? I understand --fast is just a negative compression number, why not just allow negative numbers in the command line switch?&lt;/p&gt;</comment>
