* [dpdk-users] Low throughput when pushing multiple priorities within a VLAN @ 2020-08-24 8:34 Alireza Sanaee 2020-08-24 19:17 ` Erez Ferber 0 siblings, 1 reply; 5+ messages in thread From: Alireza Sanaee @ 2020-08-24 8:34 UTC (permalink / raw) To: users 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 ^ permalink raw reply [flat|nested] 5+ messages in thread

I suggest you contact the local support team so they can suggest a proper solution.
