title: Dialogflow SDK or Dialogflow REST API, which is faster in term of response time?
body: <p>I have used Dialogflow for developing the app for Google Assistant. I have created intents and entities in the Dialogflow web GUI and I'm using a webhook response for further conversation.</p>
  
  <p>Now I want to build a chatbot that is part of an existing Android or iOS app and use the code I already wrote for Dialogflow as part of this. What do I need to be aware of when I do so? It looks like I can use the SDK for that platform or make calls to the Dialogflow REST API. Which is faster or are there any tradeoffs? Can I use the Dialogflow NLP without going over the network?</p>
