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 Am 11.02.2019 um 14:44 schrieb Jose Abreu: > Hello, > > On 2/9/2019 1:09 AM, Martin Blumenstingl wrote: >> (it's interesting that the sending direction has 445 retries) > I saw this before and I think it was related with COE.
