I am generating a 11GBps (Giga BYTES per second) UDP traffic using the CISCO Trex tool, to evaluate the performance of the BF2 DPU.
I am trying to make my DPU configuration as simple as possible by connecting the p1 and pf1hpf directly via an OVS bridge. I am making the bridge as shown below:
ovs-vsctl add-br newbr ovs-vsctl add-port newbr p1 ovs-vsctl add-port newbr pf1hpf
my bridge configuration is as follows:
Bridge newbr Port p1 Interface p1 Port pf1hpf Interface pf1hpf Port newbr Interface newbr type: internal
then I am monitoring the traffic using the system activity report tool (sar) using this command:
sar -n DEV 1 --human
I notice that the OVS bridge is only able to forward a maximum traffic of 500MBps as per the screenshot below:
as you notice from the screen shot above the traffic arriving on p1 is 10.9GBps while the traffic arriving on pf1hpf is only maxing out at 500MBps.
could you please explain why this is happening, and how to go about fixing this issue.
