Model: TL-SG3428X  
Hardware Version: V13
Firmware Version: 1.30

Good day

Yesterday I got my SG3428X

My PC is connected via 10gbe sfp+ to the switch, same for my 2 NAS
and when i copy a file from my pc to any of the Nas i get ~230mb/s transfer

without the switch
direct connection pc to nas
i get ~750mb/s transfer

I saw Jumbo in settings within omada software controller
but i only can set it global from 1518 to 9216 (my 10gbit cards are set to 9000, my 1gbit is 1500)

changing the Jumbo value doesnt help, but I like to understand would 9216 or 9000 the correct value at the switch, and why is there no different value between 1gbit and 10gbit ports for a Jumbo setting

Anyway..main issue...a lot to slow connection, when the switch is between the devices

Thank you for your post.
Could you please tell us the exact model of the SFP+ modules you are using? Have you tried any other modules?

Also, how are you measuring the file-transfer speed? I recommend running iperf between the PC and NAS to see what throughput you actually get. You can check the port status to confirm that both sides have negotiated 10 Gbps Full-Duplex.

MTU is not “the bigger the better”; an excessively large MTU can increase latency and the probability of errors. MTU size has no direct relationship with the negotiated link speed. If you do raise the MTU, make sure every device in the path supports the same jumbo-frame size.

Have you applied any special configuration to those two switch ports? In addition, you can capture packets to investigate where the bottleneck occurs.
