nfs cifs performance

  • hallo,


    after a lot experiments with tmp mounting nfs4 and cifs shares i get following results on the same client hardware:


    file size: 12 GB


    windows7 cifs: upload: ~115 MB/s
    download: ~115 MB/s


    mint16kernel3.13, cifs: upload: ~ 58 MB/s
    download: ~ 62 MB/s


    mint16kernel3.13, nfs4: upload: 25MB/s, little decreasing
    download: ~115 MB/s


    can anyone tell me the reason about the slow transfer speeds on linux os?

  • If you would tell what kind of machine your mint16 is, we maybe can tell you more.


    PS: Nice, you broke my cifs record, if that 115MB/s is an accurate number.


    Greetings

  • Hi David,


    es handelt sich um ein Acer Asphire V5-573G i5-4200U,8GB,128GB SSD. Realtek network (mint16driver:r8169, firmware:rtl8411-2_0.0.0.1) Ähnliche Werte unter mint16 habe ich, soweit ich noch in Erinnerung habe, auch auf desktop intel dq77kb,xeon-E3-1245v2 16GB,128 SSD,intel network.
    Da die hohen cifs Raten auf dem Acer bei einem realem w7 erzielt wurden (keine VM), dachte ich es ist unabhängig von der Clienthardware. linux läuft auch nativ per multiboot...


    Grüße

  • Verbunden über einen ggf. zwei D-Link DGS-1005D Switches, Router spielt auf dem Weg nicht mit, Cat7 TP.
    Sportlich, kann sein, soweit man bei cifs unter w7 der Explorer Anzeige trauen kann ;) cpu last serverseitig upload: ~50%, download ~30%

  • nfs over my desktop (itel nic): download: ~115MB/s, upload: ~100MB/s.
    Unfortunately there is also a decreasing of transmission in the upload. Eventually a ssd caching problem on the mint16 desktop?! ssd is reading continously, an after
    short time the ssd reading often stops and the transmission falls. The same on notebook, but with much slower transmission. In this time, no desktop handling is possible.
    A Problem with the nfs Protocol?

  • Schwer zu sagen. Ich hab im moment wenig Zeit sonst wuerd ich selbst mal eine suche anstreben. Sebastian, kannst du nicht mal ne google suche anwerfen "mint (16) nfs cifs slow"?


    Gruss
    David

  • it seems to be a problem with the ntfs extra option: with option async, the client and transmission freezes, and slow and degrading transfer speed when copying large file to server are better. Is this option wise
    and whats the reason about the success with this option?
