When connecting my MacBook Pro via Thunderbolt 3 to the QNAP TVS-672XT, my write/read speeds are consistently in the region of 830/1200MB/s (verified using Black Magic Speed Test), but when I use the 10GBase-T interface, write speeds remain consistent with the Thunderbolt 3 interface (830MB/s), but read speed drop way down to just 400-450MB/s.
I tested the 10GBase-T link speed from my MacBook Pro > Akitio Thunderbolt 3 Dock Pro > QNAP LAN 1 using iPerf3, and it reports Bandwidth for both directions at 9.35Gbits/sec, so nothing wrong with that.
Can anyone help or offer a suggestion on what might be going on? I can't understand why the 10GBase-T interface can keep pace with the Thunderbolt 3 interface for write operations, but slows so badly on read (I know 10GBase-T can't match Thunderbolts 1200MB/s read, but I would expect it to be in the region of 900MB/s).

Re: TVS-672XT Slow 10GBase-T Read Speed
Thanks for that, but I think my issue is different. I'm not using a built-in Apple 10GbE adapter but the one built in to my Akitio Thunder 3 dock. iPerf3 tests report my MacBook (via the dock) to QNAP bandwidth (both ways) is 9.35Gbits/sec (probably as good as 10GbE gets), so I'm confident it isn't the Akitio or QNAP 10GbE hardware causing this problem.

Re: TVS-672XT Slow 10GBase-T Read Speed
I done some more tests but this time created a new non-QTtier share (the tests above were to a Qtier share) and this time tested using SMB, AFP, NFS and Thunderbolt 3.
SMB: 600Mbps Write / 450Mbps Read (+/- 50Mbps)
AFP: 600Mbps Write / 800Mbps Read (+/- 50Mbps)
NFS: 660Mbps Write / 680Mbps Read (very consistent)
Thunderbolt 3: 720Mbps Write / 1320Mbps Read (very consistent)
I ran Black Magic many times for each connection type but there was very little variation.
SMB is the worst performing for Read by some margin with NFS / Thunderbolt 3 being the most consistent. I don't know what's going on but I'm quite sure it isn't the 10GbE hardware.

Fixed it. SMB is now running as it should
For those interested, I removed Qtier, deleted the Virtual LAN switch and rebooted. On startup I re-enabled the Virtual LAN switch and setup Qtier again making sure to enable Jumbo frames on the QNAP and MacBook.

Thanks for the feedback.
I'm having quite the same issue but I don't use qtier.
But my question is, how did you delete and re-enable virtual switch ?
Thanks a lot !

Hello
It seems problem comes from macOS Catalina. I've just installed Big Sur from scratch, and problem has disappeared !
I will check in the next few days...
