We have a big problem right now. We have employees using Flybooks with an UMTS connection. Over this UMTS connection they are using a VPN connection and a Citrix ICA client. Due to some problems with the ICA clients in combination with the UMTS, we've switched some of the employees from the ICA client to the RDP 6.0 client.
Yesterday we received the monthly bill for the UMTS connections and it scared the **** out of us. The RDP employees use up to 10 times more bandwidth than the ICA employees. The RDP sessions are set up with minimal parameters (256 colors, no themes, etc. etc.). How is it possible that the bandwidth is ten times as much?
