Curious if anyone else has run into this issue - I’ve now tried both Proxmox and TrueNAS Scale on bare metal, and can’t seem to get my full symmetric gigabit speed to the internet on a speedtest-cli run. I’m getting right around ~950mbps+ down, but only around 100-300mbps up depending on which driver I use (virtio vs. intel e1000).
For anyone who may be experiencing this issue, I think I’ve discovered the source:
I was using the 10Gtek SFP+ adapter (Amazon.com) that others have mentioned on this forum to connect my HL15 to my network. I switched to a DAC (SFP+ to SFP+ directly) and that solved the issue. It seems that there may be some incompatibility on the upload speeds between this adapter and my Ubiquiti switch. I suppose I’ll return it and see if I can find one that does work.
Hi @c1rcaa , Could you try using the 10Gtek SFP+ with your unifi switch again? I’m pretty sure I’ve had that setup work, but I think I may have had to turn off auto negotiate on the unifi switch and set it 1000.
