     It is probabily for my weak charger/psu. I only need 0.5a but my weak charger/psu only get 4.88v at 0.45a. With an estimated vdroop of 0.2-0.3 with my usb cable ( 1 meter, not AWG20... ) my orange pi probabily get 4.6v. I am not very sure, I am going testing that some days.

    At last the guilty was not my weak charger/psu, the issue was at client side. My PC, my samba client, connects to 2.4Ghz wifi sometimes and connects to 5Ghz wifi anothertimes. 2.4Ghz -> poor network throughput, 5Ghz -> good network throughput.
    It was not a kernel problem, nor power/hardware issue. It is my fault, sorry for confusion.

    Another time poor network throughput with last kernel ( 5.37.180117 - 4.14.18-sunxi64 ). Is it possible to select another kernel ?

     

    Thanks in advance

    At last It was an issue in my PC, at samba client side.  My PC connects to 2.4Ghz instead of 5Ghz one

     

    Thanks in advance

    No - only passive inside a black cube Raspberry Zero Case - but my Opi Zero Plus is almost idle :)
    You could see my "modified" black qube cas here:

     

    
    but my case does stand on the side (heat can flow away and the room temperature is aroud 20 degree):

    As attachment some temperatures - out of my NodeRed Dashboard - to compare :)

    uooohhhh!!!!!   What a tiny "big" CPD!!!!!  ;-) Thank you very much, guidol. It is a very good reference for me.  Now, I have moved my orange pi zero plus H5 to a very  open-space ( it was inside a very closed furniture before.... ). I have moved it behind my plasma TV ;-).  And now, almost idle, temperature is in normal values ( with 21C room temperature ):

    I use my OP Zero for NAS Server ( samba/nfs ) and for p2p downloads with mldonkey.

     

    You can see my brico-project with an old celeron heatsink ( I am very worried with temperatures, perhaps I am a little friki... ):

    hello,

     Trying last kernel, 4.14.8-sunxi64, I am getting a very poor network throughput, only 3.98MB/s via samba.... Before that, I got 30MB/s ( via samba with my USB 2.0 HDD as bottleneck ).
     Furtheremore, I see a max CPU Freq at 812Mhz ( before 1Ghz ) and very high temperatures at idle... Perhaps CPU Freq Scaling is not fully implemented. I am very excited with this little board and I am sure
     I am going to see some improvements soon. I had been using an Orange pi One with armbian for one year very happy. This board, Orange Pi Zero Plus, is my gigabit upgrade as NAS. Great distro armbian!!
     
     Thank you armbain-team!
     
     Best Regards

     Hello again,

     

      New kernel, new news. I am getting very good network throughput again with last kernel 4.14.10-sunxi64. I am getting 30MB/s transfer speed with my config, via samba with an USB 2.0 HDDD as bottleneck. Great!!
