March 20, 20224 yr Hey all. New to Unraid. Long story short my Write speeds are 1000gbps but my read speeds are around 150mbps give or take. Is there any way to improve this? I have a 10gbe port and a 4tb SSD cache so that's why the read is pretty fast. I'm wanting to use this primarily for video editing so that's why the speed is important. Let me know. Thanks! tower-diagnostics-20220320-1240.zip
March 21, 20224 yr Community Expert Start by running an iperf single stream test to check that everything is performing normally with the LAN.
March 22, 20224 yr 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.

March 23, 20224 yr 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?

March 25, 20224 yr 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. Edited March 25, 20224 yr by Kubernetes
