title: Chartjs doc examples are lightning fast but same code is slow when reproducing
body: <p>Why are the example in the Chartjs documentation smooth and really fast, but when I try to reproduce it locally (same code, same browser (Firefox), <strike>same Chartjs version</strike>) it is considerably slower ? I tried using a Chrome-based browser as well, got the same issue.</p>
  <p>Code from <a href="https://www.chartjs.org/docs/latest/charts/doughnut.html" rel="nofollow noreferrer">Chartjs doughnut example</a> :</p>
  <pre><code>  new Chart(document.getElementById(&quot;graphe&quot;).getContext('2d'), {&quot;type&quot;:&quot;doughnut&quot;,&quot;data&quot;:{&quot;labels&quot;:[&quot;Red&quot;,&quot;Blue&quot;,&quot;Yellow&quot;],&quot;datasets&quot;:[{&quot;label&quot;:&quot;My First Dataset&quot;,&quot;data&quot;:[300,50,100],&quot;backgroundColor&quot;:[&quot;rgb(255, 99, 132)&quot;,&quot;rgb(54, 162, 235)&quot;,&quot;rgb(255, 205, 86)&quot;]}]}});
  </code></pre>
  <p>Here is how it looks like (it's not just the gif compression, it really is that slow):</p>
  <p><a href="https://i.stack.imgur.com/ODhYV.gif" rel="nofollow noreferrer">Fast (in documentation)</a></p>
  <p><a href="https://i.stack.imgur.com/nPJx7.gif" rel="nofollow noreferrer">Slow (locally)</a></p>
  <p>Am I missing something here that'd explain such a speed difference ?</p>
