body: <p>We have started to use spring aop for cross cutting aspects of our application (security &amp; caching at the moment). </p>
  
  <p>My manager worries about the performance impact of this technology although he fully understands the benefits.</p>
  
  <p>My question, did you encounter performance problems introduced by the use of aop (specifically spring aop)?</p>
