When using netcat to transfer a 5 gb file from one VM to another VM, the resulting throughput was
ubuntu@ip-10-73-143-203:~$ time sudo bash -c "(nc -w 3 ec2-50-17-13-245.compute-1.amazonaws.com 1234 < /mnt/bf)"
real 2m56.656s
user 0m1.612s
sys 0m15.088s
the throughput was 5000mb/176sec = 28.04 mb/s
