title: How to resolve "long time" to render template, "timeout error", "multiple users error" issues in Flask?
body: <p>I am building a website using Flask to then be hosted on <a href="https://www.pythonanywhere.com/" rel="nofollow noreferrer">pythonanywhere.com</a>. My website is perfectly fine when running on the localhost server. Since my backend process takes a lot of time to process (which cannot be changed) hence rendering template also takes time, furthermore, I am facing timeout issues in gunicorn servers Flask, and due to these long refreshing time periods, many users can not access the website simultaneously. </p>
  
  <p>Can someone please let me know how should I handle this issue ?</p>
  
  <p>I tried the below code, but it doesn't solve my issue.</p>
  
  <pre><code>if __name__ == '__main__':
  app.run(threaded=True)
  # Alternately
  # app.run(processes=3))
  </code></pre>
  
  <p>Could you please assist me?</p>
