Router is CCR1036 v6.29.1 with ~110 static simple queues . The routers job is only queuing and nothing more .
Normally queuing uses 10~20% cpu usage and router's cpu usage is 20~30%
There is an open Ticket#2015063066000326 but staffs suggestions was not useful for me .
Start by running this command:
"/queue interface set [find] queue=default-small"
Check performance after that.
I think that problem is caused because few queues have very many packet marks
specified for them. I suggest that you either merge packet marks or divide queue
