# Efficiency Reporting and Follow-Up Review
|
|
|
|
Load this reference when the user asks what changed, wants a before/after report, or asks for another pass over remaining expensive jobs.
|
|
|
|
## Reporting Rules
|
|
|
|
- Separate expected savings from measured savings.
|
|
- Do not claim exact time or cost savings without before/after run data.
|
|
- Call out confounders such as cache warm-up, changed matrix breadth, runner changes, or unusually small PRs.
|
|
|
|
Use this phrasing when data is incomplete:
|
|
|
|
`I can report the efficiency mechanisms that changed, but I cannot honestly claim exact minutes saved without comparing before/after GitHub Actions runs.`
|
|
|
|
## What To Measure
|
|
|
|
Gather:
|
|
|
|
1. A baseline sample before the change
|
|
2. A post-change sample after caches warm
|
|
3. Per-workflow or per-job duration comparisons
|
|
4. Avoided runs, skipped jobs, or avoided matrix legs
|
|
|
|
Always separate:
|
|
|
|
- PR wall-clock time
|
|
- Total runner time across jobs
|
|
- Work avoided entirely
|
|
|
|
These answer different questions. A change can reduce runner spend without materially improving the fastest feedback path.
|
|
|
|
## Follow-Up Review Pass
|
|
|
|
After the first round of fixes is validated, inspect the remaining expensive jobs:
|
|
|
|
- Compare setup time versus execution time
|
|
- Identify heavyweight wrapper actions and confirm what they really enforce
|
|
- Review whether each matrix dimension still serves an active decision
|
|
- Recheck after caches warm
|
|
- Break down the dominant slow step before proposing further changes
|
|
|
|
Keep the follow-up compact. Report the next few highest-value opportunities, not a long wishlist.
