title: Starting an app with android studio 'instant run' is very slow
body: <p>I just enabled instant run for my project. Building and uploading is faster but my app startup time has increased from a few hundreds of milliseconds to a few seconds.</p>
  
  <p>I'm generally happy with that compromise. I just wanted to know if I was the only one noticing this and if there can be any chance to optimize that too ?</p>
