Model: TL-SX3008F  
Hardware Version: V1
Firmware Version: 1.0.1 Build 20220623 Rel.38240

Hi all,

 So I got this switch a week ago and I have been struggling with getting good speeds from it. The switch shows I am connected at 10gbe and the connected NICs also show 10gbe, but I am only hitting speeds of 200mbytes writing to NAS between two NVME SSDs. When I connect directly, I get 850mbytes. The connections are via a 2 meter DAC cable from the switch to the NAS and a 20ft Fiber cable connecting via SFP+ transceivers to the PC. I have also tried CAT6 from the PC to switch also with no luck.
The transceivers are not TP-Link but the ones I bought are listed to work with TP-Link products.
I have also tried the switch standalone and also with Omada, with no effect (Jumbo frames do not seem available using Omada).

Is there some setting I am missing on the switch which is affecting the speeds? If I can't resolve this I will have to return the switch and probably go with a Microtik one instead.

Can anyone help?

Thank you for your feedback. Could you please help me check two more things?

1. Does the switch port show 10G speed on the Controller->Devices->choose the switch->right menu page?

Specially the port connected to the NAS;

 

2. Did you enable LAG/LACP function on the NAS? If so, please try to disable it;

 

3. If you have two PCs, please follow this FAQ to run Iperf test and share me the test result

The NAS is an Unraid server, it does not have LAG/LACP enabled. All connections are showing 10g Duplex connections. I have done iPerf3, the results are below. Unfortunately I am getting no where close to those speeds in real world performance. In my testing I have done a fresh install of Windows, but as stated originally, I get great speeds between the two connections when the switch is not in the equation.

btw, the NICs are Mellanox MCX311A-XCAT CX311A ConnectX-3 EN in both machines.

  @PatrickMcC As an additional update, I got 2 TP-Link 10gbe transceivers and I still have the same issue. I plugged the two TP-Link transceivers into the switch with fiber running to both PC and server and used 6COMM transceivers on those to the NICs.

Still no joy. I have gone ahead and ordered a Mikrotek switch which will be here mid next week and if that works, I will be returning the TP-Link switch.

  @PatrickMcC Hi. Did you manage to test the new switch from Mikrotik?
