詳細なタイミングデータを使用したパフォーマンス解析

Fiddler Everywhere by Telerik is a cross-platform web debugging proxy designed to help software developers monitor, inspect, and modify HTTP and HTTPS traffic between their applications and the internet. It provides comprehensive tools for troubleshooting network-related issues, analyzing application performance, and testing web applications under different network conditions, streamlining the development and debugging process.

The Fiddler Everywhere v5.21.0 update introduces a redesigned Timings view, enhancing its utility for performance analysis across various protocols. This new feature offers a granular breakdown of the timing phases for individual sessions, including standard protocols like HTTPS and bidirectional protocols such as gRPC. By examining detailed metrics like DNS lookup duration or server response time, users can precisely identify bottlenecks and performance issues. The ability to compare two sessions side by side simplifies the process of isolating discrepancies and understanding differences in performance. These improvements make the tool indispensable for developers and network engineers working to optimize application and network performance across diverse communication protocols.
