Dear all,
I'd like to push two flows with two different priorities from a NIC to
the network. If I use same priority for my flows, they'll be pushed at
the line rate. However, when I pick two different VLAN priorities,
throughput reduces drastically.
Is there anything wrong with my NIC configuration?
Thanks,
Alireza

Hi,
We have examined three NICs:
Ethernet controller: Mellanox Technologies MT27800 Family [ConnectX-5]
Ethernet controller: Mellanox Technologies MT27710 Family [ConnectX-4 Lx]
Intel Corporation 82599ES 10-Gigabit SFI/SFP+ Network Connection
Our DPDK version is 20.05.0-rc0, Intel NIC works properly and doesn't
show any throughput slow down, however, Mellanox NICs both show dramatic
slow down for some reason.
Thanks,
Alireza

Hi,
I suspect it is related to the egress QoS policy mechanism enabled by
default on the ConnectX. I suggest you contact the local support team so
they can suggest a proper solution.
