title: How many calls can a PHP Nominatim API respond to each second?
body: <p>I have setup a PHP Nominatim API on an Amazon R3 Linux instance. (15GB ram 2VCPU etc. (its a pretty fast computer))</p>
  
  <p>Approximately how many API calls per second can I expect it to respond to?</p>
  
  <p>I am planning on making 40 million reverse geocode API calls in total and need to know how many times to call it each second.</p>
