Subject: Re: [dpdk-users] Low throughput when pushing multiple priorities within a VLAN

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
