title: wagtail admin super slow page loads
body: <p>I have an existing django 3.0 project that I've integrated Wagtail 2.10.2 into. Wagtail seems to be working ok but the wagtail admin is super slow. The user facing pages themselves are fine.</p>
  <p>Django debug toolbar shows that the delay is due to the browser request taking 5 - 8 seconds for each page load. The time panel shows 74601 involuntary context switches (5 voluntary.)</p>
  <p>This is happening on a localserver. I have only a handful of wagtail page objects and the database size is small.</p>
  <p>I've run <code>collectstatic</code> and all the GET requests are either <code>200</code> or <code>304</code>.</p>
  <p>Can anyone help?</p>
