Try instantiating 20 Kontakts in your sequencer, and see if you get the same saving speed.
Thanks, Martin. I'm so stupid that I have not tested this simple case. I will try this this evening when I'm back at home.
Anyway, do you think it would be an idea to implement a button "Disconnect/Reconnect all instances" in the server instances window (see below). Of course this button should remember which instances (of VE Pro Server) belongs to which VST instances (in the sequencer). But then you could easily disconnect (for very quick saving and loading) and reconnect.
