That was rather much. Okay, so then we know that you have some latency,
and a larger sliding windows will improve the situation. But, as you
noticed, doubling improved it, but beyond that, there was no change, so by
then you were getting as much data as you possibly could. The bottleneck
is then no longer at your end. It's either the ISP ftp-server, or the
ADSL-modem, or some router in between that don't feed you more data.

(As a comparision, a large ftp-server, which is not exactly next-door, but
still in Sweden, gives me a ping-time of about 17 ms, and that is 14 hops
away.)

:-) Your ISP folks probably don't even know what we're talking about.

Huh? Correct me if I'm wrong, but didn't you say 240 KB/s and 160 KB/s.
That's nothing like 2 or 3%...
