title: How can improve http request performance on an iOS device during App start?
body: <p>I have an iOS app where I need to load a lot of stuff (JSON data, Images ...) initially after app start (after appdelegate calls the first view). Currently I am using AFNetworking for my requests (Async requests).</p>
  
  <p>What I experienced is a big delay before the first request (3G connection - iPhone 4)  itself really starts. I measured the time from operation start to the first bits loaded and checked the answering time of the server. It takes between 2.5 and 4 seconds before the app even starts receiving the first bytes, server said the buildtime is about 0.03 seconds. I think that is a big delay, even if he might have to establish the 3G connection first.</p>
  
  <p>I tested this also with other servers, methods (synchronous/asynchronous), with AFNetworing and simple NSURLRequest and it is always the first request that takes a lot of time. </p>
  
  <p>So my question is, did anyone else experience this and is there a way to accelerate that?</p>
