Public bug reported: Hello, Recently i've found out that linux-htb is hardcoded to QoS section in neutron-agent's code. For a small workloads it's enough but in case there is 200+ interfaces this makes overall performance to suffer due to high irq. I guess we could try to use mqprio in order to balance tc's flows over multiple queues but is it supported scenario for neutron-agent ? I'm really not sure that DPDK able to help in this case.
Conditions: OpenStack Zed Openvswitch (vanilla, not a DPDK) 400 interfaces with QoS on each ** Affects: neutron Importance: Undecided Status: New -- You received this bug notification because you are a member of Yahoo!
