You have optimized your website with various solutions and best practices. But are you sure your end users experience a real gain in performance? Does every user benefit in the same way if they are connecting from tablets, smartphones, or desktops? How well do user-side processing capacity, browser type and version, and network speed convey your optimizations?
Based on real customer data, we will conduct a brief analysis of the impact of a simple optimization rule, in an attempt to understand who is likely to benefit most from an improvement in web performance: tablet users with an up-to-date operating system? older browsers? slow-performing devices? This talk will address real user monitoring together with active monitoring methodologies to correlate response times with actual users' configurations.
