Fastpass is not "zero queue". They simply move queuing into other places. First, in the end host. When a host wants to transmit data, it must queue those packets and send a message to the arbiter to get a slot, it must then wait for a response, and then wait for a slot. Second in the arbiter itself, the arbiter must be able to keep up. This is easy at low load, but will get much longer at high load and larger systems.
