Hi,

How did Iperf calculate, that it sent 71.5 MBytes? I mean it says it
has sent 51021 datagrams and one datagram is 1470B so I should have
sent 75MB instead(51021*1470/10^6).

Formula

151021*1470/1024/1024

gives 71.5264 as result. Probably the printout should rather read

[  4]  0.0-60.0 sec  71.5 MiBytes  10.0 Mbits/sec

(note the 'i' in MiBytes). The (unwritten) consent in IT seems to be that the data rates (specially so at serial data transmission) should be in decimal prefixes (M = 10^6) while data volumes should be in binary prefixes (M = 2^10) ... at least in technical departments, marketing departments seem to strictly use decimal prefixes as they give slightly larger numbers.

Peace!
