title: Garbage collection tuning for Java 8 Applications
body: <p>1) Our application: Spring boot, Java 8</p>
  
  <p>2) Parameters we use: xms = 256 MB, xmx = 2 GB</p>
  
  <p>We have been seeing that used heap size of our java8 applications are not shrinking back down when appropriate.</p>
  
  <p>Any other parameters  that we should be using along with #2 above, when launching our spring boot/Java 8 application, so that GC can do a better job?</p>
  
  <p>Thanks for your help!</p>
