Severity: 3-Major


-- Lower performance in TPS. -- Increased CPU consumption for throughput.


Lower TPS performance numbers and higher CPU usage in throughput tests.


-- Running BIG-IP Virtual Edition (VE) (UNIC is the default Virtual Function Network Driver for VE). -- High data rates, perhaps particularly when connection mirroring is configured.


In case of UNIC, extra CPUs must be allocated to handle SoftIRQs for higher performance.

Fix Information
