I am having a good play with MQC and also setting up parent and child, I am implementing it on a 100 mb fast int, In a nutshell I have many sites and I would like to be able to implement different policies for each site, its a connection into an MPLS cloud and the outbound traffic cant exceed 45mb, the whole thing it isnt working very well and the processor is running at about 20% the whole time, (normally 10%), it is a 2600XM

FIRST QUESTION
Do you think I have this parent child set up ok, is this how you would do it ?

SECOND QUESTION
Is there any issues with implementing a QoS policy like this on a 100mb int (when the AR is 45mb)

Here is the config

!
! bit for defining the classes for the CORK child policy
! there would be another couple of these

class-map match-all CORKNONCRITICAL
  match access-group name CORKNONCRITICAL
class-map match-all CORKCORESERVERS
  match access-group name CORKCORESERVERS

!
! bit for defining the individual child policies
! ok we would have 2 or three more policies- i'll omit them for clarity
!

policy-map CORKCHILDPOL
  class CORKNONCRITICAL
   bandwidth 1500
  class CORKCORESERVERS
     police 500000 15625 15625 conform-action transmit exceed-action drop
  class class-default
   fair-queue

!
! bit for defining the children's classes (that sounds weird)
! for the parent policy

class-map CORKCITYCHILD
 match access-group name ALLCORKTRAFFIC
class-map CAVANCHILD
 match access-group name ALLCORKTRAFFIC
class-map KERRYCHILD
 match access-group name ALLCORKTRAFFIC
!
! now the parent policy
!
policy-map QOSPOLICY

 class CORKCITYCHILD
  service-policy CORKCHILDPOL

 class CAVANCHILD
  service-policy CHILDCAVANPOL

 class KERRYCHILD
  service-policy KERRYCHILDPOL

 class class-default
  fair-queue

!
interface FastEthernet0/0
 bandwidth 100000
 service-policy output QOSPOLICY
 speed 100
!
