After updates and reboots it also works and there are no problems?

Yes, so far zero problems (fingers crossed)!🤞 On Feb 24, 2024, at 23:39, Ilya Savin @.***> wrote: After updates and reboots it also works and there are no problems?

What about speeds? I am not able to get full 2.5Gbps neither in real disk read/writes nor with iperf.

[Sjekke]

What speeds do you get?

[anibalpedraza]

I've done some further tests and finally I am able to get full speed when single way (only sending or receiving iperf test).

However, if doing both iperf tests at the same time NAS->PC drops from 2.5 Gbps to 1.7 Gbps, while PC->NAS remains at 2.5 Gbps. Maybe some throughput limitation?

Edited: I finally solved it with parallel (-P) streams on iperf. So it seems to be fully working now.
