+1 on the BGP running over single core issue.
I have seen router with 3 full tables (IPv4 + IPv6) and convergence time goes really very slow (9-10 mins in sometimes). Also, if you make any change impacting bulk routes like e.g putting higher localpref towards routes of a specific ASN/it's downstreams then it again takes quite a while and CPU keeps on jumping in meantime. Other then that those routers are just excellent. I have worked on CCR + also using Microtik SXT for my home connectivity (wireless p2p link) bundled with map2n as CPE. Anything less bulky works really well on all these devices. Good luck!
