Slow copy from/to NAS

1. offizieller Beitrag

    Hi,


    I have a problem with network speed while copy from/to my NAS. Till today I have speeds from 80MB/s to 100MB/s (NAS, PC and switch is at 1Gbit network). Few days ago I noticed slow speed while copying files.
    Now are speeds:
    Copy from PC to NAS: max. 80MB/s (average 60-70MB/s)
    Copy from NAS to PC: max. 30MB/s


    I change nothing on NAS (no new plugins or programs). Only apply new patches for OMV. Tested another notebook/PC with 1Gbit/s network card with same slow speed :(


    Can someone help me with this problem?
    My MB is MSI B85M-E45 with Realtek® 8111G network

    I assume you have the backports kernel installed? What patches did you install?

    I was curious what patches they were. I keep my server up to date and my samba has not slowed down. If there was a kernel update, it might be caused by new realtek drivers.

    I installed new Realtek drivers after noticed speed problems. I downloaded newest drivers from Realtek webpage as mentioned in earlier post.
    I do not understand why in one direction are good speeds ane in another are slow...


    My disks are in good condition - tested it with dd and speeds are above 120MB/s

    I assume you are using samba? There are a few posts on this forum with smb tuning parameters that may help.

    There are more tuning threads out there. What Windows version are you using?

    I have Windows 7 Pro 64bit. Tested speeds on another PC with Windows 7 Pro 32bit - same slow speed.
    Now tested also on notebook with Windows 7 Home Premium and there are speeds above 100MB/s in both directions. Now i am confused...

    Windows has a lot of defaults and different settings that can cause this. Compare the two systems to see if there are any differences. Maybe even reboot the Pro box.

    Do you use the kernel firmwares for the nic?


    Zitat

    git clone git://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git
    sudo cp -r linux-firmware/rtl_nic/ /lib/firmware/
    sudo update-initramfs -u


    With this firmware i have 100 - 110mb/s.

    I tried use kernel firmware for nic but without success. Speeds are same as before.


    I think it is a bug in Windows 7 Professional because in Home Premium speeds are above 80MB/s.
    I try ask on other forums if someone can solve this problem. But if someone here can help - I appreciate it.

    While I don't have a Win7 Home box, my Win7 pro and ultimate boxes both saturate gigabit (110MB+). So, may still be a setup difference between your Win7 boxes.

    My setup:
    Desktop PC Windows 7 Pro (latest updates, Windows installed maybe 2 years ago - can be dirty maybe) - slow speed from samba to PC (30MB/s)
    Notebook Windows 7 Pro (latest updates, installed maybe 10 days ago - clean) - slow speed as on PC (30MB/s from samba to notebook)
    Notebook Windows 7 Home Premium (latest updates, installed xy years ago) - slow speed, but higher than 30MB - average 45-50MB/s
    Notebook Windows 7 Home Premium (not latest updates, clean install) - good speeds around 80 - 90MB/s


    I try to use some live Linux to test speeds on Windows 7 Pro machines

    Have you compared network settings on each box?

    Do not know what to compare. Deep settings are not compared (via regedit). Basic settings like IP, mask, DNS, GW are good - all of PCs are set to DHCP. DHCP server is my Mikrotik. All of PCs have 1Gbit/s network card.


    Can you tell me what settings to compare?

    • Offizieller Beitrag

    Yep, I was just thinking about basic settings. Not sure what else to look for.
