I think that QOS on the PIX is useless because:
1. Its policing and not shaping, which means that excess traffic is dropped
and not queued.
2. You can't do hierarchical/nested service policies, which means that the
QOS will be effective only when traffic rate will be near the MAX:
100/1000Mb
Don't know why Cisco bothered to code QOS into PIX/ASA.
