# `mix rheo.bench`
[🔗](https://github.com/thanos/rheo/blob/v1.0.0/lib/mix/tasks/rheo.bench.ex#L1)

Runs a small relative benchmark against `Rheo.Backend.ETS`.

Numbers are comparative only — not SLOs. Optional Redis/Mongo benches stay in
Livebook (`notebooks/backends.livemd`).

    mix rheo.bench
    mix rheo.bench --count 5000
