My retailer has a 100Mbps FIFO shaper that will queue up to 100ms worth of full MTU packets. Without ingress shaping, loaded latency builds up to about 95ms and then stays there for the remainder of the test. With ingress shaped to 99Mbps with cake, fast.com loaded latency peaks around 40ms, then quickly settles down to 8ms. On multiple runs of the test, the worst latency peak I saw was 60ms. So even shaping ingress close to link capacity is a huge win against a FIFO.
