That describes the DBMon benchmark [0] pretty accurately. It has a hundred "components" (rows), each with several subcomponents that re-render based on state changes.
Actually it is less interesting and indicative of mainly one aspect of web app performance, that is re-rendering. The JS Framework Benchmark gives one a more holistic overview that includes bulk insertion, deletion, swapping, events, startup time, etc.
On this benchmark, Simulacra.js outperforms React by a wider margin.
