            <title>[SERVER-16671] logging write conflicts at log level 0 is too aggressive</title>
                <link>https://jira.mongodb.org/browse/SERVER-16671</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Since write conflicts are normal in multi-threaded workload that heavily updates same documents (ex: YCSB with latest or zipf distribution), the logging of it should be significantly lower.&lt;/p&gt;

&lt;p&gt;Recommendation: &lt;/p&gt;

&lt;ul class=&quot;alternate&quot; type=&quot;square&quot;&gt;
	&lt;li&gt;LogLevel 0:  log nothing (updates with a lot of writeConflicts will be logged as slow ops if they exceed slowMS threshold)&lt;/li&gt;
	&lt;li&gt;LogLevel 1:  log update conflicts &amp;gt; 100 attempts&lt;/li&gt;
	&lt;li&gt;LogLevel 2: log update conflicts &amp;gt; 10 attempts&lt;/li&gt;
	&lt;li&gt;LogLevel 3+ : keep at current logging or log all.&lt;/li&gt;
&lt;/ul&gt;
