>From the video it looks like the issue is on GeoServer side.
There could be many reasons for that, starting from the type of data (in
the example I see you are asking vectorial datasets), how they are stored
(shapefiles or DB), connections available and memory of the DB, complexity
of styles (in this case look quite simple, unless you have a lot of rules),
cache enabled or not (in this case it seems like the cache is disabled).
If you feel comfortable you can contact me privately and share with me
passwords for the instance so I can take a first look at the settings. From
the informations I have right I cannot say much more than this currently.

Alessio Fabiani
