I'm curious about the amount of traffic going through the interconnect here. As these messages are targeted to a single processor or two processors, wouldn't this impose a large load on the interconnect?

Yes it certainly will! Especially for reasons we discuss in lecture 16, each message is in itself serialized. Think about how for each red line above, the requester needs to first ask for permission to 'have' the bus, then the arbitrator assigns permission for the requester, then the address is sent on the wire, and so on... this is most certainly a huge load on the interconnect!
