The browser wars bring fresh challenges for web designers and developers. At the application level, different browsers may load source code, images, third-party objects in different orders, leading to inconsistent presentation, poor performance, missed optimization opportunities and frustrated end-users.

The reality is that JavaScript loads and performs differently across browsers, and traditional methods for testing and monitoring cannot find and diagnose browser-specific, client-side performance problems. Today's web developer needs to be able to monitor performance as it occurs in real time on all major browser types and spot opportunities for browser-specific optimization along the way.

This session enables you to understand JavaScript behavior and performance across browsers, as well as consider object load order differences. After this session you’ll be able to assess and optimize the performance of an application across different browsers.

In this session you learn how to:

• Improve content rendering across multiple browsers and operating systems
  
• Understand and improve object load order, browser by browser
  
• Ensure that third-party content doesn’t degrade client-side performance
  
• Realistically preview performance under load in each browser
