I have got a 300mbit symmetrical fiberoptic line, and I have got to transfer a 51MBYTE tar file from HOST A (fiberoptic 300mbit) to HOST B (digitalocean machine with more than gigabit bandwith).On both side I have got nice speedtests results (300mbit on A, 700 on B) but when I scp from A to B I have got this:assets.tar            100%   51MB 220.3KB/s   03:55only 220kbit of maximium speed.But if I do from HOST B to A I have got a really nice result:assets.tar            100%   51MB   8.4MB/s   00:06    ***REALLY GOOD SPEED***What can be the issue?
