Benchmarks

Benchmark score in milliseconds per operation — lower is better. Every chart is the checked-in baseline from the repo’s own suites: same apps, same hardware, same run. Reproduce them with pnpm bench:all, and see benchmarks/ for what each suite measures.

Every suite at a glance

Start here: each cell is the geometric mean of that suite’s per-operation scores relative to Octane — 1× is Octane, below 1× is faster than Octane. Pick frameworks and a suite for the bar view, or scan the whole grid and re-baseline it to each suite’s fastest framework. The sections below have the full per-operation charts in milliseconds.

Each cell is that framework’s score relative to Octane (1×), geometric mean across the suite’s operations. Green is faster, red is slower.

Octane vs the field

Octane compiled from .tsrx and .tsx, against React 19 (with a separate React Compiler comparison where available), Preact 10, Solid, Svelte 5, Ripple and Vue Vapor — each framework’s fixture written the way its docs recommend. The ranked chips on each card are that suite’s one-line reading: every framework’s geometric mean across the card’s operations, relative to Octane, fastest first.

memo-wallMemo bail-out walls — parent re-renders against memoized subtrees, and context updates punching through them. React Compiler is shown separately from vanilla React; Solid, Svelte, Ripple and Vue Vapor have no parent re-render to absorb, so their near-zero wall ops are the fine-grained model’s honest number.

The authoring cliff

Octane against itself: what naively-authored code costs relative to the compiled fast path. The de-opt fixtures render the same apps through plain createElement — the shape every binding produces — so the cliff is a first-class, regression-guarded number.

js-framework — the authoring cliffThe same 1,000-row app authored four ways: tuned .tsrx, React-style naive .tsrx and .tsx, and plain-.ts createElement with no compiler involvement (the shape every binding produces).
