It’s probably a good idea to share my own experiences here.

It's convergence time primarily, and route table maintenance, that will be considerably more rapid on x86 due to BGP being a single core process. I have heard of people happily running two full tables on CCR1016. I would be OK with this as long it were one of a pair of edge routers, as secondary, the primary being either x86 or bigger iron, depending on bandwidth requirements. YMMV. It's fairly easy to determine what your baseline CPU level would be if you do a full table peering internally for testing. I see about 40% under profile on a CCR1009 with a single full table. (Adds and removes being fairly slow… try searching the route table for a single route via the CLI, and you'll see how painful this is!)

I have run full tables on as small as a CCR1009 with few issues, but prefer x86. For a few thousand routes, as in an IGP, BGP on CCR is completely fine.

I'm not worried about it takes a couple of minutes to build routes when it first boots up. Are the issues resolved at this point? I'm running an older x86 box for BGP and want to replace the Powercode BMU (x86) with a more power efficient unit, possibly a second CCR? Does this sound like a good idea at this point or will I have Mikrotik problems? Is there something better than the CCR for these jobs?
