hap lite perf results

On the http://routerboard.com/RB941-2nD-TC page it is claimed that the hap lite device provides ~400M routing capability on all four ports. I could suppose that it was actually for the switching mode (bridging), but second line in the performance results table claims that the same performance is achieved for the case where CPU must look at each packets due to firewall.

Could somebody point out the block diagram of the device, please ? AFAIR 8227 has only fast ethernet ports, but according to https://wikidevi.com/wiki/Qualcomm_Atheros QCA9553 has ‘integrated FE switch’. What is the bandwidth between CPU and the switch for hap lite ?

This is not quite important because it has only 100mbps ports. Are you going to route more than 100mbps with this router?
