title: Unity Android platform iOS switching is very slow
body: <p>I have a project in unity which is switched on android platform. After making some changes in android i have to often convert my project into iOS for iOS build. But the conversion process takes so much time.it takes More than one  and half hour with a dozens of <strong>try again button</strong> clicks . During conversion I came to know  that my CPU utilized 100% and the <strong>PVRTExTool</strong>.exe taking 99% CPU usage. </p>
  
  <p>What I am missing, is this <strong>usual time of conversion</strong>? My project mostly consist of panoramic textures and the conversion time is so long. How can i make it fast? and what will be the impact if i fast it somehow?</p>
