CCR2116-12G-4S+ sets a new standard of single-core performance in the whole CCR product family! There are four 10G SFP+ ports. They have a separate, full-duplex line connected to the Marvell Amethyst family switch chip. Then we have Gigabit Ethernet ports. 12 of them are running through the Marvel chip. And there is another Gigabit port connected directly to the CPU. For management purposes. Each group of 4 ports has a separate full-duplex connection to the switch chip. No bottlenecks here. You can expect switch-like throughput in most setups.
