Benchmarking guidelines using examples/benchmark and examples/benchmark-react (suite selection, commands, and what packages are exercised).
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Benchmarking ## Node benchmark (`@examples/benchmark`) When working on performance investigations or changes that might impact **core, normalizr, or endpoint** (no browser, no React), use **`@examples/benchmark`** as the canonical harness. ## React benchmark (`@examples/benchmark-react`) When working on **`packages/react`** or comparing data-client to other React data libraries (TanStack Query, SWR), use **`@examples/benchmark-react`**. - **Where it lives**: `examples/benchmark-react/` - **How to run**: From repo root: `yarn build:benchmark-react`, then `yarn workspace example-benchmark-react preview &` and in another terminal `cd examples/benchmark-react && yarn bench` - **What it measures**: Browser-based init/update duration, ref-stability counts, sorted-view (Query memoization), optional memory (heap delta), startup metrics (FCP/TBT), and React Profiler commit times. Compares data-client, TanStack Query, and SWR. …

How to install
mdr add reactive/data-client/.cursor/rules/benchmarking.mdc@sha256:690b158bff99f1beThe line at the top of this page pins the label git:20261006.0eece91, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
