I have a 7206VXR (NPE-G2) . At the rate of 140 kpps i gain 80% of cpu . So i looking for ways how to reduce it?

So i want to turn off netflow(but don't want to this,monitoring is highly important for me), but it will give me only 10-20% ю

At this moment with 84kpps i have 58%

sh processes cpu sorted give me this.

The major consumer of resources is the IP Input process, which implies that you are process switching. What's happening as far as the rest of your configuration? Do you have CEF switching enabled on all of the interfaces? That router should be capable of something like 10X (or better) that performance. –  rnxrx Dec 15 '12 at 3:20
    
of course the cef is enabled. the sh ip cef gives : <pre> sh ip cef Prefix Next Hop Interface 0.0.0.0/0 a.b.c.d GigabitEthernet0/1 0.0.0.0/8 drop 0.0.0.0/32 receive e.f.g.h.0/24 attached Null0 e.f.g.h.0/30 172.29.0.5 GigabitEthernet0/3 e.f.g.h.4/30 172.29.0.5 GigabitEthernet0/3 224.0.0.0/4 drop 224.0.0.0/24 receive 240.0.0.0/4 drop 255.255.255.255/32 receive </pre> –  naimson Dec 16 '12 at 12:38
    
The more telling point will come from "show int switching." Bottom line is that there's some feature that you have turned on that's process switching packets. We need more information about your configuration to figure out the cause - certain security features and QoS settings are often the cause. –  rnxrx Dec 18 '12 at 4:00
    
You can see configuration there pastie.org/5483194 . Output of show int switching is there pastie.org/5547729 –  naimson Dec 18 '12 at 15:19
    
The configuration looks pretty generic, but the "show int switching" isn't from a 7200. Try "show int st" as well. –  rnxrx Dec 18 '12 at 23:25
