siron1992 Posted November 23, 2023 Share Posted November 23, 2023 Hey All, I 'think' i'm getting slow transfer speeds from my Desktop to UnRAID (NvME Cache) - approx 50 - 60 Mbps. UnRAID is connected to router via 2.5 Gbe ports and shows as 2500 Mbps, full duplex, mtu 1500 in Unraid. Ran iperf, and Bandwidth only showing between 168 to 181 Mbits/sec. How do I improve this? alfred-diagnostics-20231123-1244.zip Quote Link to comment
ConnerVT Posted November 23, 2023 Share Posted November 23, 2023 Realtek 2.5Gbe nics have been problematic for many Unraid users. In fact, I ditched mine for an Intel nic after hours of troubleshooting the same speed issues you are seeing. It looks as you may have a RTL8125B based nic. I would try installing the RTL8125(B) PCI Drivers plugin available in CA. It may help. (I would have tried this myself before swapping in the Intel, but the plugin came available after I swapped).

No success unfortunatly Quote Link to comment
siron1992 Posted November 23, 2023 Author Share Posted November 23, 2023 Just done a both ways ipref and still the same with the Plugin and a New Cat5e Cable - 4 pairs. Quote Link to comment
ConnerVT Posted November 23, 2023 Share Posted November 23, 2023 You have confidence that the system you are using to transfer to/from your Unraid server can support 2.5Gbe fully? Same question for anything between the two (switch)? For example, my daily driver PC has a USB nic - It will receive close to 2.5Gb but only send around 1.8Gb. ITX motherboard so no PCIe slot available. Quote Link to comment

Was just tring to turning bridging off as sugegsted in another post, added the router to eth0 and now unRAID is inaccesable. Think I've just bricked my entire NAS... Quote Link to comment
