mysql5.6 mysql process uses 50% CPU all the time.

We are in the process of upgrading mysql from 5.5 to 5.6 and we have upgraded one test instance.
Test instance on 5.5 give the following top output. [COLOR=#FFF0A5]
[COLOR=#FFF0A5]
[COLOR=#FFF0A5]
[COLOR=#FFF0A5]
[COLOR=#FFF0A5]
[COLOR=#FFF0A5]
[COLOR=#13773E]
[COLOR=#FFF0A5]

Test instance on 5.6 give the following top output.
[COLOR=#FFF0A5]
[COLOR=#FFF0A5]
[COLOR=#FFF0A5]
[COLOR=#FFF0A5]
[COLOR=#FFF0A5]
[COLOR=#FFF0A5]
[COLOR=#13773E]
[COLOR=#FFF0A5]

Can you please advice what needs to be done to make CPU utilization lower in 5.6 as 5.5?

Any update about this?

Run pt-mysql-summary on 5.5 and 5.6 then paste results here.

This has been resolved after engaging Vadim (Percona CTO), thanks for your response though.
