Introduction. Third-party scripts can cause negative load-time effects. Why is this an issue? Well, in Google’s view, a poorly-optimized page should not rank highly. Instead, search results should favor pages with fundamental design strengths—including JavaScript minification, rapid execution time, and render-friendly scripting. In reflection of this belief, Google has planned the gradual release of a major update to its search algorithm that is scheduled for June through August of 2021.

Dynatrace news. AWS Lambda is the fastest growing technology for serverless workloads and helps developers innovate faster. It removes the burden of managing underlying infrastructure and is broadly adopted for cloud-native application environments. But serverless functions don’t exist in a vacuum. It’s critical that you understand how they impact your customer-facing web applications, mobile apps, or APIs and how they interact with other functions, services, and classic technology stacks.

People often tell me they don't understand performance tool output because they can't tell what's "good" or "bad." It can be hard as performance is subjective. What's good for one user may be bad for another. There are also cases where I can't tell either: The tools only provide clues for further analysis.
