Same here, 1gigabit Internet Connection (using a gigabit router now).
I provide upload services on a regular basis, on US servers for example I can upload with 3-4MB/s per file on single upload and a constant ~1MB/s on multiple uploads (10 at a time, using Filezilla).
Just to clear some heads because I see an off-topic argument here:
15Mbps = 1.875MB/s - you can setup speedtest.net to show you the speed in MB (MegaBytes) and if you reach 1.8, you are in the OP's requirements. No need to start a flame regarding data speed terminology.
Here, have a blast:
