title: Debug webpage memory and CPU usage, ideally on mobile safari?
body: <p>I have a web page which has a bug that Ive only seen on one device with mobile safari. My hunch is that its a CPU / memory issue, how can I debug this? </p>
  
  <p>In perfect world I could remotely debug this on the actual device (an iPhone 5s), however any sort of memory / CPU debugging would be helpful.  </p>
