            <title>[SERVER-22077] Improve the runtime of sharding js tests</title>
                <link>https://jira.mongodb.org/browse/SERVER-22077</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;UPDATE: In the interest of not declaring implementation, I just wanted to highlight that the goal here is twofold:&lt;/p&gt;

&lt;p&gt;1) Reducing the number of failures showing up for the buildbaron.&lt;br/&gt;
2) Taking scheduled-&amp;gt;finish patch build execution time below 2.5 hours.&lt;/p&gt;

&lt;p&gt;How we get there (splitting test suites, deleting tests, running in parallel, etc.) I leave to whomever owns this.&lt;/p&gt;

&lt;p&gt;===========&lt;/p&gt;

&lt;p&gt;I&apos;m not certain this is even the place to discuss this, but wanted to at least start the discussion.  We&apos;ve noticed a few jumps in test timing, and it seems like we should at least consider reducing those jumps where possible.  This ticket just represents the first test timing regression that I&apos;ve run down.&lt;/p&gt;

I&#8217;m rerunning them now, but it looks like one of these two commits by Kal caused &lt;br/&gt;
mongos_rs_shard_failure_tolerance.js to go from 1 minutes to 8 minutes.&lt;br/&gt;

&lt;a href=&quot;https://evergreen.mongodb.com/task/mongodb_mongo_master_enterprise_rhel_62_64_bit_sharding_WT_67b68b5f094d88753ae2fe14f6d708c9e5b4bfbd_15_11_11_15_18_34&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;https://evergreen.mongodb.com/task/mongodb_mongo_master_enterprise_rhel_62_64_bit_sharding_WT_67b68b5f094d88753ae2fe14f6d708c9e5b4bfbd_15_11_11_15_18_34&lt;/a&gt;&lt;/p&gt;

&lt;h2&gt;&lt;a name=&quot;Windows2008R2DEBUG&quot;&gt;&lt;/a&gt;Windows 2008R2 DEBUG&lt;/h2&gt;
&lt;p&gt;Same thing:&lt;br/&gt;
The first commit (and the ones before it) take 3 hours and 10 minutes&lt;br/&gt;
The second commit takes 4 hours.&lt;br/&gt;
Looks like one of those two commits increased the timing for several tests within the suite.&lt;/p&gt;</description>
