Nikolay,

when i issue command show proc cpu sorted 5min I watch next a picture

CPU utilization 5 min is 70%

answer:- This is average amount of high cpu seen by the device.

2-

Current cpu CPU utilization for five seconds: 63%/42%;

First 63% means process traffic and 42% is interupt traffic.

23 % is your process traffic which means that the packets is hitting the sotware cpu.
