title: Should I accept a 25% overhead on a Spring Boot (Jersey) request?
body: <p>I'm working on a Spring Boot REST API which uses Jersey.</p>
  
  <p>Data generated by an instrumentation tool indicates that about 100 ms. are being spent on "stuff" which happens after the invoked resource method returns. The instrumentation tool doesn't (out of the box) say what this "stuff" is.</p>

  <p>I'm wondering : for a request that takes 437 ms., should I accept that about 100 ms. (or ~25% of the total request time) goes into overhead happening either before and after the actual resource method?</p>
