With long ping times you want to split your upload into many parallel parts so the odd dropped packet doesn't bring things to a halt. Then it just depends on your bandwidth.
We were able to saturate the gigabit nic on an ec2 instance in Ireland uploading to S3 in Oregon. At that rate a 10TB will take a little over a day.
- georgerobinson 11y agoI'm puzzled. Can you explain what you mean by bringing to a halt? Do you mean a dropped packet might terminate the TCP connection; or at worst result in the timeout of a segment and a return to slow start? Nevertheless, I would have thought a timeout is a rare event at best, even on high latency links, due to the post-Jacobsen RTT estimator and fast retransmit kicking in at 3 duplicate ACKs?
