title: How powerful are mobile browsers compared to desktops?
body: <p>I plan on implementing some client-side hashing (and perhaps encryption) for an application I am building. Using the <a href="http://crypto.stanford.edu/sjcl/" rel="nofollow">Stanford Javascript Crypto Library</a> on a desktop takes <em>over a minute</em> to do some of the calculations I'm asking the browser to do in Javascript. </p>
  
  <p>I'm wondering if this is asking too much from mobile browsers like Silk, Mobile Safari, and the others. Apart from testing on most modern smart-phones - is there a general guideline of what is too much for them? Any ratio of how powerful they are to desktop browsers?</p>
