The 6to4 relay I run at my employer (AS29259) does around 200kbps on
average and maybe short bursts of up to 5mbps. The ones doing more than
100mbps are usually the relays used outbound by large content delivery
networks (the relay used by newszilla6.xs4all.nl (free binary
newsserver) comes to my mind).

This is totally manageable with Cisco routers regardless the constant
bickering about the suboptimal Cisco (IPv6) performance which would lead
you to the assumption that you can't transit a single byte of IPv6
traffic through such a box. They do work quite well these days.
