Best Practices for Front-End Performance Testing

This best practices whitepaper gives an overview of front-end performance testing. Use this paper for practical tips on how to build a scalable performance testing practice.


Web and mobile applications have become more sophisticated than ever. End users have become accustomed to consuming services via their devices and browsers, rather than physically visiting the bank, or a retail store or calling a travel agent.

But beyond simply having a web or mobile application, users expect a flawless digital experience, and this requirement is growing in importance. This represents a critical juncture for both vendors and users as a functional, well designed, and performant experience often impacts the users’ brand selection and more critically, the success of the business.

There is plenty of data that demonstrate the impact of improving frontend performance for business that want to succeed in digital:

  • According to Mobify, every 100ms decrease in homepage load speed worked out to a 1.11% increase in session-based conversion, yielding an average annual revenue increase of nearly $380,000. Additionally, a 100ms decrease in checkout page load speed amounted to a 1.55% increase in session-based conversion, which in turn yielded an average annual revenue increase of nearly $530,000.

  • DoubleClick found publishers whose sites loaded within five seconds earned up to twice as much ad revenue than sites loading within 19 seconds.

  • A tech executive at AutoAnything reported that when their engineering team reduced page load time by half, they saw a boost of 12-13% in sales.
