Recent case studies show that effective web caching depends on more than cache-hit ratio. Data layout, object compression, CDN economics, and traffic shape all need measurement before a change is scaled.

React, canvas, OffscreenCanvas, and WebGPU are not mutually exclusive choices. They serve interface regions with different update cadences, interaction needs, and rendering costs.

For high-frequency streams, the bottleneck is often the path from incoming data to pixels—not merely React render count. Ring buffers and OffscreenCanvas point to a split between data handling, UI coordination, and rendering.
