If this is still an issue for you, please provide additional information and we will reopen the ticket.&lt;/p&gt;</comment>
                            <comment id="2100295" author="schwerin" created="Wed, 26 Dec 2018 15:30:04 +0000"  >&lt;p&gt;I think putting the justification into the description would suffice. I&apos;m interested further in the future in reducing the number of round trips to the first fully authenticated RPC in the common case, both to handle connection scaling and because I still believe in the dream of &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-12143&quot; title=&quot;Make some unauthenticated commands require auth&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-12143&quot;&gt;&lt;del&gt;SERVER-12143&lt;/del&gt;&lt;/a&gt;, &quot;Make some unauthenticated commands require auth&quot;, which includes an aspiration to get most of the ismaster data into post-auth variants of ismaster only. But that will take place in a future where we&apos;ve had to more thoroughly reexamine how we handle authentication.&lt;/p&gt;</comment>
                            <comment id="2097488" author="jason.carey" created="Thu, 20 Dec 2018 18:43:15 +0000"  >&lt;p&gt;Because it has the option to (because the drivers do so), and because waiting for auth&apos;d connections adds overhead in targeting that doesn&apos;t deliver any extra user value.&lt;/p&gt;

&lt;p&gt;The pathological case is a replset with a newly elected primary on the opposite side of the earth (from our mongos).  We&apos;re looking at 2x the round trips, so 2x the wait before we start establishing connections and servicing requests.&lt;/p&gt;

&lt;p&gt;Round trips:&lt;/p&gt;
&lt;ul&gt;
	&lt;li&gt;Tcp handshake&lt;/li&gt;
	&lt;li&gt;2x tls establishment&lt;/li&gt;
	&lt;li&gt;isMaster&lt;/li&gt;
	&lt;li&gt;3x rounds of scram&lt;/li&gt;
	&lt;li&gt;isMaster&lt;/li&gt;
&lt;/ul&gt;


&lt;p&gt;I&apos;d like to make it possible for the rsm to start fielding requests after the initial isMaster.&lt;/p&gt;

&lt;p&gt;I can see a weakening of the ticket description to &quot;should be running its isMaster calls as soon as possible, including on new un-authd connections if required&quot;.   would that work for you?  (probably by extending the current isMaster hook to update the rsm)&lt;/p&gt;</comment>
                            <comment id="2094317" author="schwerin" created="Tue, 18 Dec 2018 14:38:46 +0000"  >&lt;p&gt;I&apos;d like some clarity on why we want this. I&apos;ve had it explained to me before, but I&apos;d like to see it written down. Specifically, why should the replica set monitor run its ismaster calls on un-authed connections?&lt;/p&gt;</comment>
