Which consumer grade router has the fastest wired performance (on the four rear ports)?

I'd say that all are the same, in the two speed classes:
10/100BT (Fast Ethernet)
and
10/100/1000BT (Gigabit Ethernet).

This means, of course, LAN to LAN data among the (4) ports, since most are simply switches. LAN to WAN port and vice-versa is a different story, of course.

Often, one connects a 10/100BT port on a router to a gigabit ethernet switch and to that switch all the PCs are connected.
