in fact, the npe-g1 uses a BCM1250 which is a dual CPU unit but vanilla IOS
is not able to use the second CPU for packet forwarding.  Unsubstantiated
rumour claimed that modular IOS (QNX kernel) could push about 1.6x the
throughput of vanilla IOS, as it was smp capable.  Pity it was never released.
