I think you should get better than that in ideal configuration (<10% of
drops) but that might be close to realistic anyhow.

IIRC 3560 is happy to do PBR as long as you don't want VRF and PBR at the
same time. If feature isn't in hardware in this box, you don't run
the feature, as you should be happy to see 10kpps.
