                    <description>&lt;p&gt;In &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-32946&quot; title=&quot;Multiple change streams cause severe performance drop&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-32946&quot;&gt;&lt;del&gt;SERVER-32946&lt;/del&gt;&lt;/a&gt; we saw high change stream notification latencies due to a large number of changes, a small (default) pool size, and a low notification rate on each stream. We might want to find some place in the docs to mention this.&lt;/p&gt;</description>

I&apos;ve described the PyMongo workaround &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-42885?focusedCommentId=3440615&amp;amp;page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#comment-3440615&quot; class=&quot;external-link&quot; rel=&quot;nofollow&quot;&gt;in this comment&lt;/a&gt; on &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-42885&quot; title=&quot;Registering multiple change stream watchers over single db connection&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-42885&quot;&gt;SERVER-42885&lt;/a&gt;.
