We currently have a P4/3.0ghz with dual GigE ports (one onboard, one PCI-X Intel server card) acting as our edge router. We are starting to see CPU spikes up to 50% during our peak times (150Mbps of total traffic passing thru the box). We have 6-7 queues and static routing.
What are the recommendations for a faster systemboard and CPU to handle more traffic?
