  1. How does the Matomo admin interface perform?
    Could you explain it exactly?
  2. Which version of Matomo do you use?
    4.6.2
  3. Are these requests POSTs or GETs?
    In screenshot is request with “idsite”. In logs server it’s GET requests
  4. On which browser did you try?
    it’s not matter

When you access the Matomo UI (in order to configure Matomo measurables, etc), is it fast or slow?

Also, in the HTTP console of your browser, can you check the response of the requests that are slow?
