title: Do Reserved Instances in AWS EC2 Have Better Performance Than On-Demand or Spot Instances?
body: <p>I'm considering purchasing an Amazon <a href="http://aws.amazon.com/ec2/reserved-instances/">AWS EC2 reserved instance</a>. Does any one know of any performance benefits for reserved vs. on-demand, spot instances? Or is this simply a pricing difference? Do reserved instances get spun up on VMs with less congestion and that sort of thing is what I'm thinking about.</p>
  
  <p>Thanks,
