title: Outgoing network performance (AWS)
body: <p>There an external HTTP server (located somewhere in the US), which we must communicate with. We use AWS EC2 instances.</p>
  <p>While we can buy a &quot;bigger instance&quot; to improve the internal network performance, is there a way to lessen (optimize?) the roundtrip time between our EC2 instance and the external server? Are therer any tools that could be useful?</p>
