            <title>[MAGNOLIA-9250] Investigate publication slowness on PaaS test instance</title>
                <link>https://jira.magnolia-cms.com/browse/MAGNOLIA-9250</link>
                <project id="10000" key="MAGNOLIA">Magnolia</project>
                    <description>&lt;ul&gt;
	&lt;li&gt;When publishing a node with 100 children, the server went down. Also when generating it. This does not happen when the server triggers 101 publications independently&lt;/li&gt;
	&lt;li&gt;Open 100 subnodes in the UI already takes long time&lt;/li&gt;
	&lt;li&gt;Document findings in our large scale content (&lt;a href=&quot;https://jira.magnolia-cms.com/browse/MAGNOLIA-9083&quot; title=&quot;Doc: Create a large scale content guide&quot; class=&quot;issue-link&quot; data-issue-key=&quot;MAGNOLIA-9083&quot;&gt;MAGNOLIA-9083&lt;/a&gt;) guide if applicable&lt;/li&gt;

                            <comment id="393388" author="mduerig" created="Mon, 22 Jan 2024 09:44:19 +0100"  >&lt;p&gt;&lt;del&gt;I assume &lt;a href=&quot;https://jira.magnolia-cms.com/browse/MAGNOLIA-9176&quot; title=&quot;Apply central threadpool to DelayedExecutor&quot; class=&quot;issue-link&quot; data-issue-key=&quot;MAGNOLIA-9176&quot;&gt;&lt;del&gt;MAGNOLIA-9176&lt;/del&gt;&lt;/a&gt; should improve things here. The increase in memory usage is likely from the spike in number of threads, which that ticket should significantly lower.&lt;/del&gt;&lt;/p&gt;

&lt;p&gt;Scratch that, on 6.3 we already run observation off a thread pool regardless of &lt;a href=&quot;https://jira.magnolia-cms.com/browse/MAGNOLIA-9176&quot; title=&quot;Apply central threadpool to DelayedExecutor&quot; class=&quot;issue-link&quot; data-issue-key=&quot;MAGNOLIA-9176&quot;&gt;&lt;del&gt;MAGNOLIA-9176&lt;/del&gt;&lt;/a&gt;. Guess we have to look at a thread dump to understand more.&lt;/p&gt;</comment>

Nothing bad happened, my instance stayed stable and reactive, CPU, memory and thread count were all bounded and reasonable.&lt;/p&gt;</comment>
