title: Performance impact of ng-csp directive
body: <p>Enabling content-security-policy and adding the <a href="https://docs.angularjs.org/api/ng/directive/ngCsp">ng-csp</a> directive prevents Angular from using <code>Function()</code> and <code>eval()</code> for certain optimization.</p>
  
  <p>The doc states that performance can decrease up to 30%.</p>
  
  <p>I was wondering what angular features are actually really impacted by using the ng-csp directive.</p>
  
  <p>Are there workarounds, patterns or other ideas that can reduce the cost of using that directive?</p>
