  • Very Slow Transfer Speed on Raspberry Pi 4 with OMV 5

    Hello,


    I was reading a lot for the past couple of weeks since my problems started.

    Here's the setup at home:


    Rpi4 4GB directly connected to the router using Cat5e cable - Gigabit<->Gigabit. WiFi on Rpi disabled. Memory card used: Samsung EVO Plus 128GB. RPi using original RPi power supply. First revision of RPi4 (if applicable).


    One USB3 port occupied with https://www.axagon.eu/en/produkty/adsa-st which holds 2x4TB WD Red drives NTFS formatted so they can be shared using Samba. HDD dock is powered externally - not consuming any power from RPi.


    Running on Raspbian - Deluge torrent client, jackett, plex media server. As docker containers through OMV5 have running Sonarr, Radarr, Bazarr. Pretty much Rpi is being used for media sharing with my FireTV Stick (using Kodi).


    Past two weeks it is kind of nightmare when it comes to download. Speeds are varying between 300kb/s and tops of 1.5mb/s. Previously speeds were quite far from this, varying between 4 and 8mb/s.

    Speedtest-cli shows Download: 84.06 Mbit/s.


    Tried the Sticky from Raspberrypi forums with enabling usb-device - that didn't change much. (Topic: https://www.raspberrypi.org/fo…ewtopic.php?f=28&t=245931)


    Tests show kind of good results:

    root@raspberrypi:/var/lib/deluged/config# sudo hdparm -tT /dev/sda


    /dev/sda:

    Timing cached reads: 1564 MB in 2.00 seconds = 781.88 MB/sec

    Timing buffered disk reads: 534 MB in 3.02 seconds = 176.95 MB/sec

    root@raspberrypi:/var/lib/deluged/config# sudo hdparm -tT /dev/sdb


    /dev/sdb:

    Timing cached reads: 1682 MB in 2.00 seconds = 840.92 MB/sec

    Timing buffered disk reads: 538 MB in 3.01 seconds = 179.01 MB/sec

    root@raspberrypi:/var/lib/deluged/config# sudo hdparm -tT /dev/mmcblk0


    /dev/mmcblk0:

    Timing cached reads: 1460 MB in 2.00 seconds = 730.28 MB/sec

    HDIO_DRIVE_CMD(identify) failed: Invalid argument

    Timing buffered disk reads: 134 MB in 3.03 seconds = 44.27 MB/sec




    OMV version is 5.5.0-1 (Usul) being updated almost every day with the hope that it will fix it by itself.


    Any suggestions apart from trying to reinstall?


    Thanks! :)
