Fixed In:
14.1.0, 14.0.0.1, 13.1.0.7

Opened: Feb 22, 2018
Severity: 3-Major

Symptoms

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

Impact

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

Conditions

-- 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.

Workaround

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

Fix Information

This release provides a native driver based on F5's physical platforms.
