title: Test connection latency between Amazon RDS instance and external server
body: <p>I need to test connection between a server located in my own datacenter and an Amazon RDS instance. I've tried with </p>
  
  <pre><code>time telnet &lt;dns-of-my.instance&gt; 3306
  </code></pre>
  
  <p>but it tracks the time since i've issued the command, until i've ended it, which is not relevant.</p>
  
  <p>Are there any ways of measuring this?</p>
