            <title>[GODRIVER-2071] Speed up Go driver patch builds, including integration tests</title>
                <link>https://jira.mongodb.org/browse/GODRIVER-2071</link>
                <project id="14289" key="GODRIVER">Go Driver</project>
                    <description>&lt;div class=&quot;panel&quot; style=&quot;background-color: #fafbfc;border-color: #21313c;border-style: solid;border-width: 1px;&quot;&gt;&lt;div class=&quot;panelContent&quot; style=&quot;background-color: #fafbfc;&quot;&gt;
&lt;h3&gt;&lt;a name=&quot;Summary&quot;&gt;&lt;/a&gt;&lt;b&gt;Summary&lt;/b&gt;&lt;/h3&gt;
&lt;p&gt;Various Go driver test variants currently take 10-15 minutes to complete. A full PR patch build typically takes 25-30 minutes to complete. As we add more tests, our sensitivity to test timeouts will increase and the timeliness of patch build results will decrease. We need to find a way to allow increasing test coverage without further increasing the runtime of the tests. Some possible improvements:&lt;/p&gt;
&lt;ol&gt;
	&lt;li&gt;Scale up test runner hardware to use faster CPUs.&lt;/li&gt;
	&lt;li&gt;Scale up local MongoDB clusters to use more replicas or shards to decrease operation durations.&lt;/li&gt;
	&lt;li&gt;Scale up test Atlas clusters to use more replicas or shards to decrease operation durations.&lt;/li&gt;
	&lt;li&gt;Run more tests in parallel to reduce overall test run duration.&lt;/li&gt;
&lt;/ol&gt;


&lt;h3&gt;&lt;a name=&quot;Motivation&quot;&gt;&lt;/a&gt;&lt;b&gt;Motivation&lt;/b&gt;&lt;/h3&gt;
&lt;h4&gt;&lt;a name=&quot;Whoistheaffectedenduser%3F&quot;&gt;&lt;/a&gt;Who is the affected end user?&lt;/h4&gt;
&lt;p&gt;The Go Driver team is the primary group affected.&lt;/p&gt;

&lt;h4&gt;&lt;a name=&quot;Howdoesthisaffecttheenduser%3F&quot;&gt;&lt;/a&gt;How does this affect the end user?&lt;/h4&gt;
&lt;p&gt;The Go Driver team currently spends time waiting for Evergreen patch builds, troubleshooting test failures caused by timeouts, and increasing test timeouts.&lt;/p&gt;

&lt;h4&gt;&lt;a name=&quot;Howlikelyisitthatthisproblemorusecasewilloccur%3F&quot;&gt;&lt;/a&gt;How likely is it that this problem or use case will occur?&lt;/h4&gt;
&lt;p&gt;We&apos;ve opened two tickets related to tests consistently failing in the last 6 months:&lt;/p&gt;
&lt;ul&gt;
	&lt;li&gt;&lt;a href=&quot;https://jira.mongodb.org/browse/GODRIVER-1762&quot; class=&quot;external-link&quot; rel=&quot;nofollow&quot;&gt;https://jira.mongodb.org/browse/GODRIVER-1762&lt;/a&gt;&lt;/li&gt;
	&lt;li&gt;&lt;a href=&quot;https://jira.mongodb.org/browse/GODRIVER-2070&quot; class=&quot;external-link&quot; rel=&quot;nofollow&quot;&gt;https://jira.mongodb.org/browse/GODRIVER-2070&lt;/a&gt;&lt;br/&gt;
Additionally, the duration of the slowest patch variant has increased by about 50% in the last 6 months (as documented by &lt;a href=&quot;https://jira.mongodb.org/browse/GODRIVER-1762&quot; title=&quot;Investigate macos and Windows test timeouts&quot; class=&quot;issue-link&quot; data-issue-key=&quot;GODRIVER-1762&quot;&gt;&lt;del&gt;GODRIVER-1762&lt;/del&gt;&lt;/a&gt; increasing the test timeout to 30 minutes from 10 minutes; now test variants regularly take 15 minutes).&lt;/li&gt;
&lt;/ul&gt;


&lt;h4&gt;&lt;a name=&quot;Iftheproblemdoesoccur%2Cwhataretheconsequencesandhowseverearethey%3F&quot;&gt;&lt;/a&gt;If the problem does occur, what are the consequences and how severe are they?&lt;/h4&gt;
&lt;p&gt;If a test times out, the resolution is usually to run it again and hope it runs faster. If that doesn&apos;t work, someone must investigate the root cause of the timeout, which may end up being that &quot;the tests just take a long time.&quot; If the tests timed out because they&apos;re just slow, someone needs to update the test configuration to allow a longer timeout.&lt;/p&gt;

&lt;p&gt;If the tests take a long time but don&apos;t timeout, Go Driver team members are stuck waiting for test results, possibly for hours or up to days depending on how many times unreliable tests must be run.&lt;/p&gt;

&lt;h4&gt;&lt;a name=&quot;Isthisissueurgent%3F&quot;&gt;&lt;/a&gt;Is this issue urgent?&lt;/h4&gt;
&lt;p&gt;There are currently some consistent test timeouts on MacOS (&lt;a href=&quot;https://jira.mongodb.org/browse/GODRIVER-2070&quot; title=&quot;Investigate MacOS evergreen timeouts&quot; class=&quot;issue-link&quot; data-issue-key=&quot;GODRIVER-2070&quot;&gt;GODRIVER-2070&lt;/a&gt;), although we don&apos;t know if the root cause of that problem is a specific problem or just general test slowness.&lt;/p&gt;

&lt;h4&gt;&lt;a name=&quot;Isthisticketrequiredbyadownstreamteam%3F&quot;&gt;&lt;/a&gt;Is this ticket required by a downstream team?&lt;/h4&gt;
&lt;p&gt;No.&lt;/p&gt;

&lt;h4&gt;&lt;a name=&quot;Isthisticketonlyfortests%3F&quot;&gt;&lt;/a&gt;Is this ticket only for tests?&lt;/h4&gt;
&lt;p&gt;Test and development efficiency improvements.&lt;/p&gt;
