I have slow speed in both directions

I have managed to improve matters a bit by upgrading to the latest Windows drivers from the Realtek website. I can now get a bandwidth of 1.62 Gbits/s after optimising some NIC parameters (the new driver provides far more control then Windows default driver which is dated 2015). This is still not ideal; transferring data to the new server from my backup Windows Server still saturates the resultant 1.62Gbit/s connection. There is a newer linux driver on the Realtek website but my understanding is that updating drivers outside the UNRAID release cycles is not recommended or supported.

Does anyone know if this card is supported in UNRAID? I cannot use most of Intel cards as they are mostly PCIE2 x8 and my motherboard only has a spare PCIE3 x4 slot. The alternative would be to use Aquantia (now also Marvell) chipset cards from NICGIGA or Asus which do seem to be supported but please correct me if I am wrong. Thanks

Diagnostics as requested. Thanks for the feedback so far; it does not sound good but at least I know I did not screw up (... other than buying the wrong adapters). Feedback in the forum on 10Gb cards based on the Aquantia chipset is positive and the general sentiment appears to be to bypass the Realtek based 2.5gb cards and just go to 10Gb. It is an overkill for my needs but if it works then it will be worth it. lily-diagnostics-20230404-1711.zip

I am a newbie to UNRAID; in the process of moving my 60TB data pool from flexRAID to UNRAID and would appreciate any help on the below problem. The UNRAID server is built and configured and ready for transferring the data from my backup data pool on a Windows machine. To speed things up I purchased a couple of TP-Link TX201 NICs (based on the Realtek RT8125 chipset) and created a peer-to-peer connection. Everything appeared to work out of the box. UNRAID recognised the cards instantly. Windows did the same. In UNRAID made sure the 2.5Gb/s NIC was not bonded to the existing 2x1Gb/s NICs. Then the trouble started. During testing I noticed transfer speed across the new 2.5gb/s connection were 20% or so worse than for the existing 1gb/s connection. Did some trouble shooting: Running ethtool on UNRAID confirmed that the link was at 2.5gbps Likewise using the Get-NetAdapter command in Windows I was also able to confirm that the link was at 2.5gb/s but to make sure I turned auto-negotiation off and forced it to 2.5gb/s. Ran iperf3 (10 parallel streams) and I was only able to get 670mb/s effective bandwidth on the 2.5gb/s link. Running iperf3 on the existing 1gb/s connection gave 954mb/s!!! Any help would be appreciated. Are these cards not compatible? Are there newer drivers? Bug in UNRAID? Have I missed something?
