December 4, 2025Dec 4 I have an unusual problem since i updated from 7.1.3 to 7.2.2:The max. tranfer rate over my 10GBit-LAN reaches only 450MB/sek.On the older version i reached over 1200MB/sek...Strange: I did not change the SMB-Settings (i use SMB 3.0) - but it doesnt matter what i try... i get only this value.Second thing: At the network settings, i cant see the IP of the 10GBit-LAN any more, but my network.cfg did not change...Also the network Info for eth1 (10GBit) is strangeIt has two DNS server entries (with a wrong IP-range), but the network.cfg does not because this is a direct link between my PC and unraid...Does someone know, what this could be?Thanks a lot Edited December 8, 2025Dec 8 by Zonediver

December 5, 2025Dec 5 Community Expert Try iperf with the previous version you were using, to make sure it was really the upgrade. There could have been a driver change that affects that NIC, but I haven't seen any other reports so far.

There could have been a driver change that affects that NIC, but I haven't seen any other reports so far.I think so too - but thats tricky - my unraid is a live-sys and in use 18h per day...Its possible that the ASUS-NICs are faulty - they are six years in use now...I will change the NICs in january and test how it is working after.

December 7, 2025Dec 7 Author Solution After testing and reading tonns of websites, i found the solution!The culprit is the SMB-Setting in Windows 11!On WIn 11, SMB-MultiChannel is activatet by default...This "devides" the max. bandwith in segements of 3-4.Switching this OFF gives back the full speed of a single transfer between Windows 11 and unRAID.Deactivating under Windows 11 (and 10 too):.) Open the Power Shell as Admin (important!).) Type the following:Set-SmbClientConfiguration -EnableMultiChannel $false.) Reboot WindowsNow, when you copy a large file from Windows to unraid, the full bandwith is used and the file is trasfered with over 1200MB/sek again 😉 Edited December 9, 2025Dec 9 by Zonediver
December 8, 2025Dec 8 But not make senses if mult channel enable will affect iperf test result.But iperf test not always reflect actual situation. Edited December 8, 2025Dec 8 by Vr2Io
