Performance Troubleshooting

Degradation in performance

Degradation in performance indicates that openvswitch may not be offloaded.

Verify offload state. Run: 

# ovs-vsctl get Open_vSwitch . other_config:hw-offload

• If hw-offload = true – Fast Pass is configured (desired result)

• If hw-offload = false – Slow Pass is configured

If hw-offload = false:

• For RHEL/CentOS, run:

  # ovs-vsctl set Open_vSwitch . other_config:hw-offload=true;
  # systemctl restart openvswitch;
  # systemctl enable openvswitch;
  

  
  

• Ubuntu/Debian:

  # ovs-vsctl set Open_vSwitch . other_config:hw-offload=true;
  # /etc/init.d/openvswitch-switch restart
