Yeah that one was from the working site. This is the first time i'm seeing these files so I'm not quite sure what I'm looking at. Initially I thought I mixed them up, with all the decreases in bandwidth I thought that file was the problem site and it was being throttled down. In fact that client is working, probably because it is being throttled? And that site does have limited bandwidth.
My problem site may not have sufficient bandwidth i suppose, but it's hard to rationalize it with the circuit barely being used 
Here's several more files from a single workstation that consistently has performance issues.
