the 3640 is not so powerful and the utilization may be normal. If you do "show proc cpu" you will see what is taking cpu.

When i issue the "show proc cpu" it does not show any process that is taking more % utilization.

Max any process such as "IP input" and "AFSapp1" takes not more than 4%.

Then if no process has abnormal CPU you have to live with it or upgrade to a faster router.
