SnapFire FSR Size benchmarks
What a deployment carries and what each page costs a browser.
Throughput in req/s: Responses read in full per second. Measured on Apple M4 Pro (14 cores).
Higher is better for requests per second. Lower is better for latency, memory, build time and size. Bold marks the best figure in a row and every figure within 5% of it.

Leptos and Dioxus hydrate by loading the whole app compiled to WebAssembly, so a page costs a browser this on top of its JavaScript. The other four hydrate with JavaScript alone and load none.
