For CPU utilization of idle

I have used the equipment in the following environments, but may be worried about a little.

Environment: ROS 6.4 on RB2011UAS

When operating at 600MHz rated the CPU, used average of 5%, but this wonder normal? By the way, it is a state that config is not set almost.
By to 650MHz by overclocking the CPU, it has been confirmed that it can be close to 0% as possible the CPU usage at idle.

There I would have to check the status of these?

Best regards

Hello

Take a look at the state and then to disabled for the time being.

As I told, showed that to disabled LCD, another problem occurred at all this time.
It can no longer have any connection with Webfig and winBox. However, communication itself is made of.

Where somehow, so was able to connect with Mac Telnet, were returned to enabled LCD, you can now connect and Webfig WinBox.

Do not you have to hit this problem?

Best regards
