Hi all,

On PNetLab, I installed two FlexEdge routers connected to FlexiManage. The two FlexEdges are connected to each other via two links with QoS settings. Traffic uses the best link with the highest QoS. The link is 1 Gbps, but when I run an iperf3 test to measure the bandwidth, it doesn't go beyond 100 Mbps, even though the two FlexiWAN devices are directly connected without any switch or router in between.

Could you please help me with this to get the best throughput ?

Best regards,

MM

Hi Moise,

Are you running iperf from the flexiEdge Linux host itself?
If so, these are low throughput interfaces that are mainly used for control.

Please run your traffic from a client connected to the LAN interface of the flexiEdge.

Best Regards,

In that case you might need to adjust the QoS BW on the device interface level?
