Have you gone through this link

I would not worry much about the memory usage as that value is normal, but definately high cpu is a concern, try the link above.

Re: ASA high CPU and RAM utilisation

The general deployment release 8.0.3 does have higher memory usage on average than 7.2 specially is you have threat detection and shun enabled.

8.0.3 interim release 19 seems to address these concerns by reducing utilisation quite significantly.

Are you having any performance issues with traffic passing through the appliance?

I wouldn't worry about it as mentioned it is quite normal for said release.
