Hi guys:
I would like to share a picture about my situation:
Two ccr1036 routing similar amout of traffic but with very different cpu load.
Please take a look: I can show follwing similar behaviour:

• a_tool->profile: Both routers, shows very even load distribution on 36 cpus, most usage is on routing.
  b_firewall: There is no rules at filter nor nat tables.
  c_There is one nms (librenms) polling snmp data on both devices every 5 mins.

Then I can list following comparison list:
Router A (left)

• version 6.46.2
  firewall raw rules:0
  bpg peers:9
  routes: 35 routes.

RouterB (right)

• version 6.44.5
  firewall raw rules:7
  routes: 62 routes.
  bgp peers: 4

Would like to hear your feedback regarding this issue:
Can those little differences impact so hard on my cpus ?
Is there any other thing to consider ?
What else can I do to keep my router B cpu load at lower values?
