title: Developer over Qps
body: <p>I use the free app engine but it keeps returning the following error 9 times out of 10:</p>
  
  <p>Object {0: "Developer Over Qps"}</p>
  
  <p>As I understanding, there is no limitation on the Qps, even with the free plan.</p>
  
  <p>Any way, even querying my app every 1-2s is too much apparently.</p>
  
  <p>Any idea what could be going on?</p>

  <h2>AFTER COMMENT EDITS</h2>
  
  <p>I use my google engine app to query a third party api:</p>
  
  <p>client -> google app engine -> third party API</p>
  
  <p>1- the client does an AJAX request to the app engine server.</p>
  
  <p>2- the server is a very simple php script which queries a 3rd party API and returns a JSON to the client.</p>
  
  <p>to query the 3rd party API from the PHP app engine, I use 'file_get_contents'</p>
  
  <pre><code>file_get_contents('http://api.sportsdatallc.org/soccer-t2/eu/matche...');
  </code></pre>
  
  <p>We do <strong>2</strong> queries to the 3rd party API in a short amount of time.</p>
  
  <p>It appears that the PHP google app engine returns 'Developer Over Qps' if we try to query the app engine more than 1 time very 2-3s.</p>
  
  <p>Does it sound reasonable for the free quota? I sounds very few to me, even for the free quota.</p>
  
  <p>I'm wondering if the bottleneck is:</p>
  
  <p>1- the 2 'fast' queries to the 3rd party API from the app engine php?
  2- the 'slow' AJAX query from my client to the app engine</p>
  
  <p>(This is the first time I use the app engine and I am trying to understand it...)</p>
