We run Citrix at our remote locations. We have two circuits at each location. One is a point to point for backup and the other is an MPLS circuit that is our primary. Both circuits are T-1 speeds.
We have all thin clients at our remote locations. When communication goes through the point to point circuit it utilizes much more bandwidth. Maybe 1.2 Mbps on average but when we communication through the MPLS circuit only 800 Kbps of bandwith is actually being used.
Can anyone explain this? I was thinking that maybe MPLS does a faster job of switching the packets across the WAN and that the Citrix does not need to use as much bandwidth because of this. This analyis was completed across all of our sites and in each case Citrix uses more bandwidth on a point-to-point vs an MPLS circuit. I have not had any users complain when accessing either ciruits.
What do you think is causing this?
