CF7 impact on WP execution (Performance)

Hi,
Recently i come to know about P3 (Plugin Performance Profiler).
Then i decide to check my site’s performance.

and i found that CF7 causes a high impact on WP Execution.
Here is the screenshot:

I am not saying that CF7 is bad, i just want to make it more improved.

Please take a look at screenshot or check it by own using P3.
If it is normal please ignore this post.

Note:
I am using latest version of WP and CF7.

Thanks.
