Скачать или смотреть Time to the Backend: The Hidden Delay in Your Application's Request Journey - Andrii Raikov

Ever wondered what happens to your request when you hit a button in your app? In this talk, we’ll explore an often-overlooked aspect of performance—"Time to Backend." Using real-world examples where response times were slow despite healthy system metrics, we’ll dive into how network and mobile provider delays can have a bigger impact than backend optimizations.

You’ll learn how even well-optimized backend systems can still face delays of several seconds due to network factors. We’ll introduce the "Time to Backend" metric, showing why focusing on broader network issues is more impactful than fine-tuning your code for micro-optimizations.

Join us to see how this metric helped improve monitoring systems and shift our focus from internal infrastructure to understanding the wider mobile ecosystem.

Additional notes
Understanding the True Latency Impact: It's crucial to recognize that delays from mobile networks and internet providers can significantly affect application performance, often more than backend optimizations.

The Importance of the 'Time to Backend' Metric: This new metric—tracking the time it takes for a request to reach your backend—helps identify hidden latency issues and provides more accurate insights into user experience.

Focusing on End-to-End Performance: While backend optimization is essential, optimizing the entire request journey, including network-related delays, should be a priority to ensure faster, more reliable user experiences.

Reevaluating Optimization Priorities: It's essential to shift focus from micro-optimizations to understanding and mitigating delays introduced by external networks and services like mobile providers, Cloudflare, and AWS.

Improved Monitoring and Incident Management: Creating effective monitoring tools, such as dashboards and alerts based on the "Time to Backend" metric, helps identify and address issues more quickly, reducing the impact on users.
