Can you please tell more about your setup here?
Is this capture taken only on the client?
in a seq number graph you can see that (disregarding the beginning
where it obviously first has to catch up some speed) until 5.73s the
throughput is quite ok, but then suddenly goes down to approximately
half without recovery till the end: http://176.31.253.70/tcp/
The receive window from hget seems to be *nearly* fully open, but is
changing (slightly) all the time. This I didn't expect, but I doubt
it's to be blamed for the bandwidth degradation you're seeing.
