Webflow Designer very slow

I was wondering if anyone else is experiences bad performance in the Webflow Designer and when publishing the site. Also saving CMS items appears to be very slow. I just started a new site, so there is not a lot of information that needs to be loaded, and the problem also appears with other website made with Webflow.

Also, when I click on things in the Designer, Webflow sometimes does not respond, for example when toggling the Navigator tree or checking checkboxes.

Does anyone else experience the same thing?
