That's terrible. I dont know what model that is or appropriate deploys but I think a couple of my peers use these and report similar times for their models for 500k+ routes. Still too slow. I think the single threaded nature of the routing table manip is at fault with the 36-but-slow cores (mikrotic). Im not sure how you get around this without drastically rewriting the kernel, which puts you out on your own developing new fundamental tech. I'd be more comfortable with full-cpu models (like xeon based for eg.)
