I am struggling to understand why the downloads from this server start off quickly and then suddenly drop to a crawl. I see there are "TCP windo full" messages early on in the trace, but this is only in the first 100 packets and window scaling is enabled. I was testing this by downloading a 20MB PDF file using "wget" from the client, I had to "ctrl-c" the capture to keep it below 1.5MB to be able to upload to cloudshark but I believe there is enough evidence of the issue in the following captures?

The problem seems to be in the server not being able to feed the 'pipe' fast enough.
So not a network but rather a server problem - I would say...
