  • 80MB/s in ubuntu, 300KB/s on Windows10 and Android (both Wifi)!?

    Because at the same time, I get 10-12 MB/s from all the ubuntu wireless devices I tried. Its just Windows and Android that have these problem, so I am sure that its some samba/network misconfiguration. Additionally, on windows, speed is ALWAYS EXACTLY shown as 355KB/s, which would be IMO a huge coincdence if its just a congested 2.4GHz band. Googling this 355KB/s file copying speed leads to a ton of results, but none ofnthem helped me so far.

    Addition: I analyzed the TCP traffic with tsharkr during a fast (wireless ubuntu laptop) and a slow (wireless windows10 laptop) transfer; the results do not tell me much, but there is clearly a difference:



    Fast one:


    Slow one:

    Hey guys, thanks for your answers! Even if the 2.4GHz band is crowded, I would expect a little more than just 355KB/s...


    I just dug out my old ubuntu laptop and tested the speed there: 11.5 MB/s on wireless, while Windows10 and Android both stuck at around 300KB/s, so it can't be the neighbors. Also, if you google "windows file copy 355KB/s" you get a LOT of results, so I guess this 355KB/s is not a random number, but some sort of misconfiguration.


    My updated speeds with my NAS (ext4 drive):


    ubuntu wired (NFS): 80-100 MB/s (expected)
    ubuntu wired (SMB): 70 MB/s (expected)
    ubuntu wireless (SMB): 11 MB/s (expected)
    Win10 wired: >100 MB/s (expected, only after turning large send offload off)


    Win10 wireless (SMB): 355KB/s, one out of 10 times 4 MB/s (????, the wireless card has no large send offload option)
    Android wireless (SMB): 300KB/s, one out of 10 times 4 MB/s (???)


    I am really puzzled, it seems that the network is working fine, and also the wireless network is working within its capacity, only the samba server does not work well with Win10 on wireless and android. Also, this re-occuring number of exactly 355KB/s on win10 disturbs me.

    I use OMV 4 with Samba 4.5 on and odroid XU4, and for some reason the file transfer is super slow over the WLAN.
    My test results:


    • always: 80-100MB/s transfer from an ubuntu box (wired, same rates for SMB and NFS)
    • always: 80-100MB/s transfer from Windows 10 (wired, LSO disabled)
    • most of the time: 200-300 KB/s transfer from an Android tablet (2.4Ghz WLAN), ES File explorer
    • most of the time: 355KB/s transfer from same Windows10 laptop as above (2.4GHz WLAN)
    • sometimes, the transfer speed for the two wireless devices spikes up to 4MB/s, but I haven't figured out when; it happens very rare.


    Any options in smb.conf do not seem to make a difference, I tried everything from blank to


    Code
    socket options = TCP_NODELAY IPTOS_LOWDELAY
read raw = yes
write raw = yes
oplocks = yes
max xmit = 65535
dead time = 15
getwd cache = yes

    I do not expect super high speeds and really do not care about it, but the 300KB/s makes my NAS pretty much unusable with wireless devices. Anyone an idea?
