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.
What happens in an app with multiple views on screen into the same state and multiple pieces of data updating at once is much more interesting.
Remember most of these frameworks are aimed at things that are far more 'web application' than 'web site'.
