I use DANOS with Intel XL710 10G NICs in DPDK mode for linux based routing.
If you're doing routing protocols, allocate 2 CPU cores to the control plane and then a CPU core per 10G/1G interface for the dataplane, plus an extra core for good measure. So for a 4 x 10G router taking in full routes, 2 cores for control plane, 5 cores for the dataplane. Those cores should be Intel Xeon E5-2600v3/4 or newer and faster the clocks, the better. Similar CPU core allocations if you choose TNSR.
