I'm getting better results than most who post here, 237GB in 2 days upload. Most of the time my upload averages 14-20 Mbps. I get 60-85Mbps using Dropbox or google drive uploading GB's in no time. I'm not expecting to use my entire up bandwidth but this is 1/4 of my possible speed...
Wired 1Gbps Ethernet Fios Fiber East Coast Central NJ up/down 75/75Mbps
Speedtest.net
Local server 85/95Mbps
San Diego 80/85Mbps
Berlin 81/45Mbps
Japan Tokyo 65/21Mbps
Hong Kong 60/17Mbps
Melbourne 50/16Mbps
Such slow results would mean the path to the data center is long and its far far away from NYC area... or the traffic is heavy at the data centers that the bandwidth is used up and packets are dropped or delayed.
