Hi,
i used iperf2 on my odroid c2 , since this can do duplex tests ! iperf2 -c 10.10.11.1
-i1 -d
Do you really need the exact numbers ?
NON-duplex:
4.14.29 reached 930 MBits without the -d ( duplex option ), 5.0rc5 only
reaches 600MBits there
DUPLEX:
With the -d option things get worse on 4.14.29 , 600MBits in both
directions. on 5.0rc5 this is the 500 to 600 in one direction, the other
only 150MBits.
iperf3 is not duplex capable, i didnt test the reverse option, but
duplex tests show that one direction drops in performance when the other
is busy.
Do you really need the exact output ? I need to reflash my box then
..... if needed i would do so.
regards,
Simon
