            <title>[SERVER-68388] Limit concurrency setting and update server parameter name</title>
                <link>https://jira.mongodb.org/browse/SERVER-68388</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;The limit for fetch/insert concurrency in idl is set at 128 to accommodate large instance sizes. For small instances the max value is unnecessarily high. This ticket will limit the settings introduced in &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-67185&quot; class=&quot;external-link&quot; rel=&quot;nofollow&quot;&gt;https://jira.mongodb.org/browse/SERVER-67185&lt;/a&gt; &lt;del&gt;to 2x number of cores&lt;/del&gt;. This value may be adjusted after testing.&lt;/p&gt;

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

&lt;p&gt;Setting it to 500(compile time max) instead and the IOPS/number of cpus will drive the recommended value(in the documentation).&lt;/p&gt;

&lt;p&gt;Also, change the name of the parameter from migrationConcurrency to chunkMigrationConcurrency.&lt;/p&gt;</description>
