title: How to resolve performance lag while moving objects with Box2D JS physics engine in Android browser?
body: <p>I am in planning of developing HTML5-Canvas based cross platform game targeting Android and iPhone platforms using Box2D js framework. My game contains some of good physics moves, thus I chose Box2D JS(<a href="http://box2d-js.sourceforge.net/" rel="nofollow">http://box2d-js.sourceforge.net/</a>).</p>
  
  <p>So, I recently ran some of Box2D HTML examples (<a href="http://box2d-javascript-fun.appspot.com/" rel="nofollow">http://box2d-javascript-fun.appspot.com/</a>) in my android phone/android tablet. I really felt low performance of these pages while running basic physics moves. </p>
  
  <p>Can anyone suggest how to resolve it? </p>
  
  <p>Can anyone suggest other engines that can provide good performance which must have applied physics moves like Box2D?</p>
  
  <p>P.S.: My Android tablet is having 1 GHz of processor and 512 MB of RAM. While i was running above pages, almost 240 MB was free.</p>
