After inserting the AdMob banner, the application starts to slow down. Tried everything - to no avail. What could be the problem?

I inserted an AdMob banner into my application, it began to work much slower (drop in CPU by 20%). Tested on Samsung Galaxy S III mini and Samsung Galaxy S4 BE - works equally slow. Everything was done according to the installation guide. In onDestroy, onResume, onPause everything is as it is written in them. Manipulations with AdView I spend in Fragment'e. What could be the problem? Has anyone encountered this?
