Where the minutes go (30d)
Waste detected
Biggest wins first, each with the exact config fix.
Missing dependency cache · Release
Add `Swatinem/rust-cache@v2` (the de-facto cargo cache), or an `actions/cache@v4` step keyed on `Cargo.lock`.
- uses: Swatinem/rust-cache@v2Also found: 11 more config fixes with negligible recoverable minutes: timeouts, retention, path filters
Artifacts at default retention · Release
`upload-artifact` has no `retention-days`, so artifacts keep up to 90 days (storage cost). Set e.g. `retention-days: 7`.

retention-days: 7Premium runners (macOS / Windows) · Release
macOS bills ~10x and Windows ~2x a Linux minute. The cost estimate above assumes Linux, so your real spend is higher. Move any job that doesn't need them to `ubuntu-latest`.
jobs:
build:
runs-on: ubuntu-latest # ~10x cheaper than macos-latestcancel-in-progress on a deploy workflow · Release
This looks like a deploy/release workflow with `cancel-in-progress: true`, which cancels queued runs too, so a queued deploy is silently dropped when a newer run arrives. Use a group-only `concurrency:` block on deploys.
concurrency:
group: ${{ github.workflow }}
# queued deploys run in order; none are droppedSystem packages reinstalled every run · Release
System packages install from the network on every run with no cache. Cache them (cache-apt-pkgs-action) or check whether the runner image already has the tool.

version: 1.0No path filters on triggers · Integration Tests
Runs on every push/PR with no `paths:` filter, so docs-only changes still trigger full CI. Add a `paths:` filter if that's common.

The matrix expands to many parallel jobs per run, multiplying billable minutes, often more combos than you need. Trim the axes, or use `include:` to list only the combinations that matter.

The cache restores only on an exact key match, so any lockfile change means a full cold download. Add a `restore-keys:` prefix line for partial restores.
