If you can think of a public ftp server with high latency I would be more than happy to dig deeper into this issue, perhaps there's more that can be done client side.
sorry to reply late.

pushd interface tcp

# End of TCP configuration
for different values on tcp buffer size i will wait for the cross-pacific fiber freed before futher tests. under heavy time period no matter how i tune the parameters the speed doesn't go up.

if you are in the u.s i can provide you a server in china, which should produce enough latancy to test.
