I am pretty sure that the problem is the driver used in unraid. When I boot debian linux with 'apt install firmware-realtek' the speed is 1Gbs in both directions. Howevery, I tried another cable (different manufacturer) without success. I don't have other switches than ubiquiti, so I cannot test with another switch. But I tried with cross over cableling and this also doesn't improve the speed with unraid.

Hey Ronan, thank you for your reply and suggestion. Unfortunately it doesn't help to speedup the speed.

I would like to request an driver update for the Realtek Ethernet Network Card: Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller Currently there is the driver firmware rtl8168g-2_0.0.1 02/06/13 used: ethtool -i eth0 driver: r8169 version: 5.15.30-Unraid firmware-version: rtl8168g-2_0.0.1 02/06/13 expansion-rom-version: bus-info: 0000:03:00.0 supports-statistics: yes supports-test: no supports-eeprom-access: no supports-register-dump: yes supports-priv-flags: no As I can see on a Debian 11 linux there is a more recent driver firmware available -> rtl8168h-2_0.0.2 02/26/15 : sudo ethtool -i eno1 driver: r8169 version: 5.10.0-11-amd64 firmware-version: rtl8168h-2_0.0.2 02/26/15 expansion-rom-version: bus-info: 0000:03:00.0 supports-statistics: yes supports-test: no supports-eeprom-access: no supports-register-dump: yes supports-priv-flags: no The reason for this request is, that the upstream speed is reduced by around 30%. More details in my Thread here: Thank you!

It seems the driver in unraid is from 2013. On another linux server with debian with same NIC the driver is from 2015. How can I make a request to update the driver?

My unraid NAS does have a Realtek onboard NIC: [10ec:8168]03:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd.

Does anyone have an idea why the transfer speed is so different? What could I do to have the same experience for downloading from NAS as I do have when uploading?

I have bought 2 USB Ethernet Adapters, one with another RTL Chipset (but not appearing in unraid) and one with AXIS Chipset. I have the same network experience as with the rtl8168 network card. Now I have not ideas anymore what the reason for this is.

I think it is related to the NIC. I did another iperf test with reverse mode, and this time I get exactly the same network speed when doing transfers from NAS to my computer c:\> iperf3 -c 192.168.1.5 -R Connecting to host 192.168.1.5, port 5201 Reverse mode, remote host 192.168.1.5 is sending [ 5] local 172.28.219.7 port 48698 connected to 192.168.1.5 port 5201 [ ID] Interval Transfer Bitrate [ 5] 0.00-1.00 sec 84.9 MBytes 712 Mbits/sec [ 5] 1.00-2.00 sec 85.7 MBytes 719 Mbits/sec [ 5] 2.00-3.00 sec 85.8 MBytes 720 Mbits/sec [ 5] 3.00-4.00 sec 88.7 MBytes 744 Mbits/sec [ 5] 4.00-5.00 sec 86.6 MBytes 726 Mbits/sec [ 5] 5.00-6.00 sec 86.1 MBytes 723 Mbits/sec [ 5] 6.00-7.00 sec 87.4 MBytes 733 Mbits/sec [ 5] 7.00-8.00 sec 87.6 MBytes 735 Mbits/sec [ 5] 8.00-9.00 sec 87.1 MBytes 731 Mbits/sec [ 5] 9.00-10.00 sec 86.7 MBytes 727 Mbits/sec - - - - - - - - - - - - - - - - - - - - - - - - - [ ID] Interval Transfer Bitrate Retr [ 5] 0.00-10.00 sec 869 MBytes 729 Mbits/sec 0 sender [ 5] 0.00-10.00 sec 867 MBytes 727 Mbits/sec receiver iperf Done. My NIC is a [10ec:8168]03:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (rev 0c) Could that be the issue? Any idea how to fix this? I would be willing to buy a USB Ethernet Adapter, but I don't know which one works best with unraid. A search in the forum was not a help. Update: I have the same NIC in another computer with debian 11 and with better speed. I compared the drivers and it seems the one in unraid is much older. Any suggestion how to update for testing?

You can install iperf3 via the Nerd Pack App in Unraid

Very interresting as I have the same problem. I have 1000gbps network and get 115MB/s for upload to unraid, but when I download the same file (or even others) I get only 80MB/s. iperf shows that network is good in both directions: ➜ ~ iperf3 -c 192.168.1.254 Connecting to host 192.168.1.254, port 5201 [ 5] local 10.0.0.185 port 50514 connected to 192.168.1.254 port 5201 [ ID] Interval Transfer Bitrate [ 5] 0.00-1.00 sec 112 MBytes 944 Mbits/sec [ 5] 1.00-2.00 sec 112 MBytes 939 Mbits/sec [ 5] 2.00-3.00 sec 112 MBytes 936 Mbits/sec [ 5] 3.00-4.00 sec 111 MBytes 935 Mbits/sec [ 5] 4.00-5.00 sec 110 MBytes 926 Mbits/sec [ 5] 5.00-6.00 sec 111 MBytes 930 Mbits/sec [ 5] 6.00-7.00 sec 112 MBytes 940 Mbits/sec [ 5] 7.00-8.00 sec 112 MBytes 937 Mbits/sec [ 5] 8.00-9.00 sec 111 MBytes 932 Mbits/sec [ 5] 9.00-10.00 sec 111 MBytes 929 Mbits/sec - - - - - - - - - - - - - - - - - - - - - - - - - [ ID] Interval Transfer Bitrate [ 5] 0.00-10.00 sec 1.09 GBytes 935 Mbits/sec sender [ 5] 0.00-10.01 sec 1.09 GBytes 931 Mbits/sec receiver So I am also interrested in finding a solution for the slow read speed.

Yes Rocket Raid is x1. My transfer is going to the array directly - cache drive not used in that case.

I am looking for advise how to distribute the disks across the controller ports and if memory upgrade will also help for better performance. Here is my setup: PCI Devices: [1103:2300]02:00.0 SCSI storage controller: HighPoint Technologies, Inc. RocketRAID 230x 4 Port SATA-II Controller (rev 02) [8086:0f23]00:13.0 SATA controller: Intel Corporation Atom Processor E3800 Series SATA AHCI Controller (rev 0c) Disks: [0:0:0:0]disk SanDisk Ultra USB 3.0 1.00 /dev/sda 30.7GB [1:0:0:0]disk ATA Samsung SSD 860 4B6Q /dev/sdb 1.00TB [2:0:0:0]disk ATA WDC WD20EFRX-68E 0A82 /dev/sdc 2.00TB [4:0:0:0]disk ATA WDC WD20EFRX-68E 0A82 /dev/sdd 2.00TB [5:0:0:0]disk ATA WDC WD20EFRX-68E 0A82 /dev/sde 2.00TB [6:0:0:0]disk ATA WDC WD20EFRX-68E 0A82 /dev/sdf 2.00TB I have 4 SATA-II Ports on the RocketRaid Controller, and 2 SATA-II Ports on the onboard Controller (E3800). Currently I have all 4 WDC Disks connected to the RocketRaid Controller to be used as my Array with one Disk as Parity. The SSD is connected to the onboard Controller as Cache. EDIT: But I don't use Cache for my transfers I am not happy with the performance as I reach 115MB/s upload data transfer only in the beginning of the transfer, but more worse only 80MB/s for download data transfer. The system does only have 8GB Memory at the moment and I wonder if an upgrade to 16 GB will help with the performance. In addition I consider to change the disk connections to distribute the load between the RockerRaid and the onboard Controller better. Maybe it is better to have the Parity Disk and one data disk connected to the onboard Controller, and the SSD connected to the RocketRaid Controller? Any advise is very welcome! EDIT: I configured the Rocket Raid Controller as JBOD

Thanks, that helped me to increase speed from 860MBits/sec to 930MBits/sec
