Here’s a VM receiving around 5.3 Gbps.
The system can coalesce all packets onto one CPU for processing efficiency.
The VMs traffic has grown to about 21 Gbps, which is more than a single CPU can handle.
The system expands the traffic across additional CPUs as necessary (and available) – In this case 5 - to maintain the demand for traffic.
