Performance Troubleshooting
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
