May 29, 20206 yr Specs: Asrock Q1900-ITX with J1900 processor Realtek RTL8111GR 16GB DDR3 1x12 TB parity 2x10TB + 1x12TB hd storage No cache drive Unraid 6.8.3 Gigabit Fiber ISP I'm new to unraid, and have had a great experience so far except my NIC speeds are prohibitively slow. NZBGet typically downloads ~ 10 MB/s. I ran a speedtest with my docker service disabled to prevent overloading cpu/ram. CPU was ~10% at idle, and tons of free ram: I then plugged my old Thinkpad into the same lan cable, and repeated the speedtest: Any idea how to fix this slow NIC speed? I ran windows/linux/xpenology on this box in the past. Most recent was xpenology, and it would download ~90MB/s on NZBGet. Have never had any issues with the NIC being slow like this, which makes me think that maybe the driver support for my Realtek nic is possibly really terrible? Edited May 29, 20206 yr by TeddyTux
May 29, 20206 yr Community Expert You should post your systems diagnostics zip file (obtained via Tools >> Diagnostics) attached to your next post so that we can see what is going on with your system.
May 29, 20206 yr Author I've attached the systems diagnostic zip as requested! Thanks diagnostics-20200528-2248.zip Edited May 29, 20206 yr by TeddyTux
July 24, 20205 yr Author Can any insightful people offer an opinion, please? I moved forward and purchased an unraid license because I liked the software. But still suffer with the slow speeds. My motherboard has one pcie x1 slot. I’m considering buying an Intel EXPI9301CTBLK Nic to drop in there. That said, I don’t want to blindly buy a NIC, if that isn’t the real problem.

LAN is testing normally with iperf between unraid server and my hardwired laptop. I added an Intel gigabit pci nic to rule out issues with the onboard realtek nic. I also reran diagnostics and attached them after the new hardware was added. Anything else I can try? untux-diagnostics-20200728-2006.zip Edit: I tried to test iperf speed between my unraid box and a public iperf test server. Results looked good- see below. Then I thought maybe my usenet provider was the culprit, so I installed Transmission linuxserver container, and downloaded the latest Ubunutu release. I clocked 25-27 MB/s. Still far slower than 80+MB/s I was getting when running synology software on the same hardware, but a huge step in the right direction. Thoughts? Edited July 29, 20205 yr by TeddyTux
July 30, 20205 yr Author Is it possible that it’s simply because I don’t have an SSD cache drive and I’m writing directly to the array?
