Hello everybody!

I have ASR1006 with two 10Gbps ports. 

If  payload of interfaces about 20% I get 0.2-0.5 ms ICMP-replay throw ASR1006.

If  payload of interfaces about 65% and above I get delay 20-40 ms . CPU payload about 60-70%.

On ASR1006 were instaled vpdn, nat, qos, rip, ospf.

asr1000rp2-advipservicesk9.03.05.00.S.152-1.S.bin

How can I reduсe delays on ASR1006?
