Subject Re: 75% time spent in handleResponseInternal() reasonable?
Date Tue, 23 Dec 2014 17:06:34 GMT

The first part of the handeResponseInternal is the call to the URLConnect.getResponseCode().
  That’s likely where most of that time is spent.   It pretty much blocks until the service
has returned a response.   It’s really just waiting for the server side to finish.

You can flip to using Async methods and the async based transport which would allow the main
threads to continue, but that can certainly change the entire programming model.
