thheller Posted January 19, 2023 Share Posted January 19, 2023 I'm only getting half speed when downloading from my new Unraid 6.11.5 Server. Uploading to it gets the full Gbit, but downloading doesn't. This is my first time using Unraid, so I'm not sure where to look. I found the other topics talking about realtek nics, but I have a Intel NIC. Tried a different Port on my Switch and a different Cable. Other PCs on my network get full speeds in both directions between each other, but always only half downloading from Unraid. Tested with iperf3 and openspeedtest running in Docker on the server. # lshw -C network *-network description: Ethernet interface product: Ethernet Connection (2) I219-V vendor: Intel Corporation physical id: 1f.6 bus info: pci@0000:00:1f.6 logical name: eth0 version: 00 serial: 2c:fd:a1:6f:23:4f size: 1Gbit/s capacity: 1Gbit/s width: 32 bits clock: 33MHz capabilities: pm msi bus_master cap_list ethernet physical tp 10bt 10bt-fd 100bt 100bt-fd 1000bt-fd autonegotiation configuration: autonegotiation=on broadcast=yes driver=e1000e driverversion=5.19.17-Unraid duplex=full firmware=0.2-4 latency=0 link=yes multicast=yes port=twisted pair promiscuous=yes speed=1Gbit/s resources: irq:149 memory:f7500000-f751ffff # lspci -v 00:1f.6 Ethernet controller: Intel Corporation Ethernet Connection (2) I219-V Subsystem: ASUSTeK Computer Inc.

JorgeB Posted January 19, 2023 Share Posted January 19, 2023 Iperf results suggests a network problem, could be NIC, cable, switch, configuration of even client PC. Quote Link to comment
thheller Posted January 19, 2023 Author Share Posted January 19, 2023 (edited) I tested with 3 different client machines, all showing the same behavior. I also ruled out the Switch and Cable, since I swapped the connection between the 2 machines sitting next to each other. From my Windows PC I can get full speed to one machine, but not the Unraid one, regardless of cable/port. I also sort of ruled out the NIC itself, since I just plugged in a ubuntu desktop live usb and booted from that instead of Unraid. With the iperf3 server then running on my Windows machine I still don't get full speed but much closer.

thheller Posted January 19, 2023 Author Share Posted January 19, 2023 Hmm, just tested again on the Unraid system and now I get closer to the Ubuntu speeds. So, I guess its the NIC. iperf3.exe -c 192.168.188.5 -R Connecting to host 192.168.188.5, port 5201 Reverse mode, remote host 192.168.188.5 is sending [ 4] local 192.168.188.3 port 65346 connected to 192.168.188.5 port 5201 [ ID] Interval Transfer Bandwidth [ 4] 0.00-1.00 sec 95.8 MBytes 804 Mbits/sec [ 4] 1.00-2.00 sec 96.8 MBytes 812 Mbits/sec [ 4] 2.00-3.00 sec 96.9 MBytes 813 Mbits/sec [ 4] 3.00-4.00 sec 97.1 MBytes 815 Mbits/sec [ 4] 4.00-5.00 sec 97.5 MBytes 818 Mbits/sec [ 4] 5.00-6.00 sec 97.4 MBytes 817 Mbits/sec [ 4] 6.00-7.00 sec 97.6 MBytes 819 Mbits/sec [ 4] 7.00-8.00 sec 97.3 MBytes 816 Mbits/sec [ 4] 8.00-9.00 sec 97.2 MBytes 815 Mbits/sec [ 4] 9.00-10.00 sec 94.3 MBytes 791 Mbits/sec - - - - - - - - - - - - - - - - - - - - - - - - - [ ID] Interval Transfer Bandwidth Retr [ 4] 0.00-10.00 sec 970 MBytes 814 Mbits/sec 0 sender [ 4] 0.00-10.00 sec 968 MBytes 812 Mbits/sec receiver Guess thats a good excuse to upgrade to 10GbE Quote Link to comment
JorgeB Posted January 19, 2023 Share Posted January 19, 2023 Could also be the NIC driver/settings. Quote Link to comment
thheller Posted January 19, 2023 Author Share Posted January 19, 2023 Anything recommended I can check/configure? I'm out of ideas. Quote Link to comment
JorgeB Posted January 19, 2023 Share Posted January 19, 2023 See the Tips and Tweaks plugin, there are some network related settings that sometimes help. Quote Link to comment
thheller Posted January 19, 2023 Author Share Posted January 19, 2023 Can't get the above ~800mbit any higher, but its good enough for now. Tried a couple combinations of buffer sizes/flow control/offload, but nothing seems to make a difference. I'll see if I can figure something out if it goes to ~500 again. 1 Quote Link to comment
