Js Framework Benchmark
This project is a suite of analytical tools for quantifying web performance, specifically designed for benchmarking the rendering speed and memory usage of various JavaScript frameworks. It provides a standardized set of DOM manipulation tests and a comparison tool that uses weighted geometric means to measure efficiency across different web implementations.
The benchmark harness distinguishes itself by providing deep analysis of DOM reconciliation strategies, comparing the performance and correctness of keyed versus non-keyed rendering. It also includes a memory profiler for tracking allocations and leaks during repetitive update cycles, as well as a bundle size analyzer to measure network transfer weight and time to interactivity under simulated mobile constraints.
The project covers a broad range of performance analysis categories, including rendering duration from trigger to paint, memory consumption tracking, and startup metrics. It further ensures data integrity through structural HTML smoke tests that verify implementation correctness and framework classification.
The tool generates result tables and visual comparisons to track performance trends and changes across different versions.
