Howeird is completely correct. Sure enough, you can get cpu processor
speeds from the gear fact sheet, but this is a poor indicator of how the
box is going to perform under load. There are simply too many factors
effecting actual throughput to use this metric for anything except a
stripped-down router. This is why routers, switches, etc. are rated on
PPS.
