Not sure how funky your QoS configurations are, but we're seeing around 65% on an NPE-G2 running at 500Mbps with MQC doing inbound/outbound policing, DSCP and EXP remarking and classification. 600Mbps of traffic on an NPE-G1 is already as much as the box can probably do. Adding MQC to forwarded traffic could have some adverse effects, like what you're seeing. We don't do NBAR, so I can't offer any feedback there. Cheers, Mark.
