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.
