&lt;p&gt;I was just chilling, working on something else, when a friend messaged me:&lt;/p&gt;
&lt;p&gt;&amp;ldquo;Hey, your app is super slow. Like, really slow. Is something wrong?&amp;rdquo;&lt;/p&gt;
&lt;p&gt;I didn&amp;rsquo;t think much of it at first. Maybe a database query was acting up. Maybe there was a memory leak. Normal stuff.&lt;/p&gt;
&lt;p&gt;Then I checked my VPS dashboard.&lt;/p&gt;
&lt;p&gt;CPU usage: 95%.&lt;/p&gt;
&lt;p&gt;For the past few days.&lt;/p&gt;
&lt;p&gt;That&amp;rsquo;s not normal. My little 2GB droplet usually sits at 5-10% CPU running a few Node.js apps and some databases. 95% means something is working really hard.&lt;/p&gt;</description></item></channel></rss>
