Police Limit bandwidth not accurate on PFC QoS

[fly]

7609 rsp720 pfc3cxl 6748 lan card

and I config ingress egress police same time on interface SVI
i config on two interface which in different vlan，and config ingress/egress qos police to 20m，but i found can’t work 
I can’t find hit in show policy-map interface

and download and upload speed is almost as same as before I config ingress egress police on the two interface vlan
 
please see config

Two test computer connect to same slot 1 6748 line card

and I made another test

i connect client computer to slot 1 6748 card and put port in vlan4043

and download file from internet which connected to slot 7 es+ card

and I config ingree egress police limit bandwidth to interface vlan4043

i found when I configure police cir to 20m,but download speed can up to 60m

i config police cir to 1m,but download speed can up to 30m

this is weird

is there any problem on 6748 line card pfc qos?

I found problem ,here.

aggregate police has been config out of resource, so new police can't work

show platform hardware capacity qos
QoS Policer Resources
Aggregate policers: Module Total Used %Used
3 1024 1024 100%
6 1024 1024 100%
8 1024 1024 100%
9 1024 1024 100%
Microflow policer configurations: Module Total Used %Used
3 64 1 1%
6 64 1 1%
8 64 1 1%
9 64 1 1%

although we config egress/ingress police on intreface vlan ， but show mls qos ip vlan can‘t find it worked only 1023 aggregate police supported.

another question:but why just config egress police on slot 1 card, interface vlan 1000 (there is no port in vlan 1000 on other card)and we found  ingress/egress police on slot 3? according cisco doc egress police implement on ingress card, but why we found egress police on slot 3?
