Can you share some numbers regarding the resources you need for hosting?  
How much RAM, CPU are you normally using.

Also, how is the user experience, how fast does it load - are there bottlenecks in some areas?

I’m asking because I want to secure conversations between patients and medics:

The only solution I found so far by reading the documentation is to: create a category for the user via API create a group for the user via API assign the pationt group, the medic and the staff groups to the category This way, the patient can and the medic can have interactions that only they can see. Also more medics could be added to the discussion and they would see the discussions. Staff can oversee for abuse.
