Question / Help low uploadtraffic while streaming

[streamingnoob]

i have a verry bad uploadspeed (0,9mb/s at speedtest.net) so i cant stream in good quality, but now i m wondering about why my uploadtraffic ticks so low in windows7 and 'NetMeter Evo' Programm while streaming (not only preview mode) or is there a difference between uploadtraffic and uploadspeed/bandwidth?

would be greate if someone could explain this to me :)
