What is the correlation between setting $compileProvider.debugInfoEnabled to false and improving performance in AngularJS 1.3?

After reading the documentation on the angular website regarding debugInfoEnabled, I'm still a bit confused. How exactly does setting 

$compileProvider.debugInfoEnabled(false)
in the angular config result in improved performance by removing element-level class bindings like ng-scope and ng-isolated-scope?

I would greatly appreciate it if someone could explain how turning debugInfoEnabled to false in $compileProvider can lead to a performance boost. I'm looking for clarification on this feature of Angular 1.3.

Any assistance in clearing up my understanding would be highly valued. Thank you in advance :)

Directives in your DOM elements play a crucial role in Angular's compilation process. These directives can be elements, attributes, classes, or comments.

When Angular encounters a directive during compilation, it follows the logic defined by that directive to make necessary changes, updates, manipulations, or perform tasks requested by the directive.

For instance, ng-repeat directives are responsible for generating multiple DOM elements based on the provided data.

Removing certain directives like ng-scope and ng-isolated-scope prevents Angular from executing unnecessary logic at those points, ultimately leading to improved performance.
