[X2Go-User] loadbalancing with x2go broker

Hello Since on http://wiki.x2go.org/doku.php/wiki:advanced:x2gobroker:loadbalancing site isn't too many information about load balancing I have question how exactly this load balancing is working? Connection client <-> broker and broker <-> server is up till client disconnect from server or this connection exist only on time of creating connection between client and server? How many clients can be handled by broker in same time? Is it possible to use x2go for around 1k clients connected simultaneously when every one of them generate pretty big network traffic? Or should we consider other load balancing solution? Usage of how many x2go servers is recommended for this number of users? Greets, Gafi
