I guess he was talking about big-iron border gateways. I could imagine that their performance suffers compared to IPv4 simply because of the longer addresses and more bookkeeping required.
OK, possibly, but I thought IPv6 was designed to simplify border routers. The addresses are 4x as large as IPv4, but the header is only 2x. And routers don't need to recompute checksums when decrementing the
hop counter. See http://en.wikipedia.org/wiki/Ipv6#Simplified_processing_by_routers
