9. Cache effect/Performance

10. Measuring throughput
drops
breakpoint
capacity
overload
overload

11. Overall Effect Inelegant handling of heavy net loads System collapse
Scalabiity affected
System and number of NICS
A single hogger netdev can bring the system to its knees and deny service to others
