title: Google calendar API service account rate limit
body: <p>I have a google service account setup for their calendar api, but it seems as though I can only make 5 requests per second. I've only figured that out from trial and error, there are no per second rate limit settings on my developer console settings. </p>
  
  <p>I have 'queries per day' and 'queries per 100 seconds per user', both of which are currently set to 1,000,000.</p>
  
  <p>I'm definitely not hitting these limits, so I can only assume there is a hidden 'per second' rate limit that is being applied. Does anyone know if that is the case?</p>
  
  <p>Thanks!</p>
