(
PAN-OS 11.0.3 and later 11.0 releases
) Lockless QoS —In Lockless
QoS mode, the firewall supports both QoS and non-QoS traffics, where the
Lockless QoS shapes the QoS traffic. The firewall shapes the packets from
the same interface (or port) by the same core for achieving Lockless QoS.
For firewalls with higher bandwidth QoS requirements, the Lockless QoS
dedicates CPU cores to the QoS function that improves QoS performance,
resulting in improved throughput and latency.
In Lockless QoS mode, as
the members in a LAG have to be mapped to the same core, the overall LAG
QoS throughput is limited by the per core throughput.
We support Lockless QoS mode on the following firewall models.
Regardless of the type of QoS configured, the maximum bandwidth (maximum
rate of transfer) you can allocate at the port level and QoS profile
level for the following platforms is 10G.
