Question to RB5009 owners

Thu Apr 20, 2023 9:40 pm

I wanted to buy RB5009 but started reading reviews and people are complaining about 2.5gb port acting slower than 1gb/s. I do not see anywhere comment that it was resolved so I have question to RB5009 owners - is that issue resolved or do you see speed issues on the 2.5gbe port?

I have seen those reports as well.

I have a VLAN trunk between AX3 and RB5009 humming nicely at 2.3-ish Gbps when using internal iperf test (can't go external, I only have a 500/30 line at home :lol: ).
So I do not really know where the issue is.

Sorry for digging up an old thread. But I think the issue was if you use the 10GB sfp+ port at the same time as the 2.5GBe port then the 2.5GBe was essentially degraded to a 1GBe port. Can anyone confirm that this is no longer an issue? I have a use case for the rb5009 and want to confirm it won't be a problem or I should just get a lower end CCR model.

Depends on how you have the ports configured.
If you have stuff "switching", like vlans etc then you should get full wirespeed.
Else if you need to process traffic then the bottleneck is that 10Gb full duplex link to the cpu plus any load on the cpu itself..

I can max out the 2.5G Ethernet port using speed test to my core router no problem. (I am not using the SFP+ port)

Yep that totally makes sense, can't expect to transfer more data concurrently than the fattest pipe allows. Just wanted to make sure there wasn't some issue that would prevent a scenario like transferring 5Gb/s through the sfp+ port and 2.5Gb/s through the 2.5GBe interface simultaneously since the total throughput is just 7.5Gb/s, assuming the CPU can handle it etc etc etc.
