title: What is the difference between latency and response time?
body: <p>I started to read famous Martin Fowler book (Patterns of Enterprise Application Architecture)</p>
  <p>I have to mention that I am reading the book translated into my native language so it might be a reason of my misunderstanding.</p>
  <p>I found their definitions (back translation into English):</p>
  <p><strong>Response time</strong> - amount of time to process some external request<br />
  <strong>Latency</strong> - minimal amount of time before getting any response.</p>
  <p>For me it is the same. Could you please highlight the difference?</p>
