I have encountered this before on a 48 CPU sun machine.
2 CPUs we set aside for network traffic, but this was because the server was under a heavy network load

Subject: Interrupt fencing on Sun
On a 8 node 10.2.0.3 RAC with 128 cpus Sun and Veritas have recommended that the customer set aside 2 cpus on each node for processing network interrupts exclusively.
This was suggested after a situation where VCS was unable to process cluster heartbeat messages in a timely manner due to Sun attempting to process the network interrupt thread on the same CPU which was running the cluster communication thread.
I would like to know if any other large customers have set aside cpus exclusively to handle network interrupts and if so what percentage of total CPUs
