Slow LAN connections on RBR50?
Hi, I'm just wondering if anyone else has encountered this issue, or if it's just me. The problem - very slow LAN transfer speeds between devices connected through an Orbi satellite. Configura...
This is not my experience with the RBR50. I have one desktop connected directly to a RBR50 LAN port and another desktop connected to a gig switch the is connected to the RBR50. When I run iPerf3, it records 949mbs in both directions. Considering TCP overhead, this seems to be "full speed".
Also, my impression is that the Orbi CPU is not involved in LAN to LAN data traffic. I telnet into the Orbi and run the "system activity report" (sar) and watch while I begin an iPerf3 test. Percentage CPU use does not change. My guess is that the "switch module" is a stand-alone chip that know which traffic stays in the LAN module and which has to be passed to the CPU.
Using the cheap gig switch achieves the same thing (data transfer stays within the switch).
I have no answer for what can be causing this phenomenon with your Orbi LAN ports. The standard question is, "Have you tried rebooting the switch?"
Thanks for the reply. I was curious about other people's experiences, as I thought the same as you - that these days, a simple switch module is likely just one self-contained chip, and the actual Orbi unit wouldn't really have to do much. But overhead there was the only explanation I could think of.
I have indeed tried restarting the whole Orbi system, with no change - but hey, can always try again. Honestly, at this point, the issue is fixed with the addition of the extra switch, so I probably won't worry much about it. It was mainly a question of if this was 'normal' with the Orbi, or not.
Thanks,
Dirk
