The screens of the component benchmark with TsButton.tsx, a Button written in TSX (drawn exactly like the Rust Button of the benchmark's own UI set, test/ui, with the default theme):
GridTs.tsx: 200 Buttons in a scroll view; the first press target updates every title.RowsTs.tsx: a recycled list of 1000 rows with a Button each.cargo test --release -p nsh-engine --test engine bench_components -- --ignored --nocapture prints the JS and core time of each screen with both Buttons; nsh test examples/bench/GridTs.tsx --trace shows the mount items.
