CI performance dashboard #1182
Description
Maintained by the CI profiler routine, which runs every 4h. Each run replaces this body and carries the history rows over.
Headline (run 2026-10-18 00:15 UTC)
Window: 2026-10-17 00:15 → 2026-10-18 00:15. The run list covers the whole window (102 runs; 42 CI runs: 39 pull_request, 1 merge_group, 1 push, 1 nightly). 1 PR merged (#1590, 10-17 14:47, enqueue → merge 7.93 min); none since. Landing is waiting on reviewers, not on CI.
- No new issues. Nothing closed. Nothing new cleared the bar. Posted the daily update on #1512: 10-17 had 8 slow-start jobs out of ~420 sampled (~2%, all in one 17h run), against 71–77% in the 10-16 slow spells.
- One new full PR run since the 20:16 profile: 39069805587 (21:10), 7.43 min to
ci-ok, 29 jobs, 31.3 L job-min, max queue wait 0.02 min, max start-up gap 6 s (fast hosts).coverage5.92, Gradlee2eleg 4.42. - No failed jobs and no re-runs. One PR run (10-17 08:02) was cancelled by a newer push (~30 L job-min).
- Nightly 10-17 05:44 green (39007350942, 24.15 min). The 10-18 nightly hasn't started yet.
Sample: all 102 runs in 24h. Job detail (filter=all) fetched for the 1 new full PR run; everything else is carried from earlier profiles (same runs). PR push → ci-ok uses run created_at → updated_at of full successful runs (ci-ok is the last job). No job logs read (no slow outlier). About 10 REST requests.

Top PR jobs by minutes (unchanged shape): coverage (5.75–6.18), Gradle e2e leg (4.42–5.08), e2e_vex_build/pip leg (2.6–3.03), e2e_redirect_npm_build (2.55–2.80), hosted-e2e (~1.55), yarn-classic / yarn-berry 4.18.0 (1.3–1.6), clippy (1.3–1.5), e2e-build, node-addon, lint-ecosystems.
Critical path (unchanged): clippy → coverage → ci-ok, in parallel with e2e-build → Gradle e2e leg → ci-ok.
Other items watched, not filed (below the bar, unchanged): per-leg overhead in the e2e matrix; Install Rust; sharding coverage or splitting the Gradle leg (~1 min); nightly Windows test shards at 22–25 min (nightly only); superseded PR runs (1 in 24h, ~30 job-min); the merge-queue fail-fast watch job (8 GitHub-hosted job-min per mg run, ~1 run/day now).
Merge-queue settings (ruleset 24668460, read 00:15): unchanged: build 5 / merge 5, min wait 5 min, ALLGREEN, timeout 90, SQUASH. Required checks ci-ok, clippy.

Open ci-perf issues by ROI
ROI on one scale: (thousands of job-min/day weighted Linux ×1, Windows ×2, macOS ×3, plus 1 per critical-path or PR-latency minute) × confidence ÷ effort (S=1, M=2, L=3).
| ROI | issue | saving | status |
|---|---|---|---|
| ~2.5 | #1512 (settings) slow Depot hosts | ~2–3 min on each merge that hits a slow host (1 of 5 merge_group runs in 24h, 11.12 vs 8.17–8.88), plus ~0.5–3.5 min on PR feedback | Slow hosts at 17h–23h on 10-15 (24–75% slow-start), 05h in the nightly (77%), and 15h on 10-16 (71%). 00h–09h on 10-17 were fast, including the nightly (0/92). 10-17 as a whole: ~2% slow (8/~420, all in one 17h run, +0.4 min). Last update: comment (10-18 00:15). Close if the next busy day stays under ~5% slow. Needs a human to raise it with Depot. |

Method notes
- GraphQL is blocked in this environment, so merge-queue state comes from REST timelines of merged PRs. The timelines use the last enqueue before the merge.
- Jobs are fetched with
filter=all. Queue wait = jobstarted_at−created_at; skipped jobs are excluded. "Start-up gap" = jobstarted_at→ first stepstarted_at; over 15 s counts as a slow host. - Critical path = merge_group run
created_at→ci-okcompleted_at. - Daily job-min = per-run mean × 24h run count per event. This run one page covered the whole 24 h (100 runs), so no scaling was needed. Merges per day come from the closed-PR list.

[agent] There are now two open dashboard issues: this one and #1175, both titled "CI performance dashboard" and labeled
ci-perf-dashboard. The body says it is maintained in place, so the profiler routine should update one issue rather than open a new one each run. I'm not closing either one, because I can't tell which issue the routine will update next. Whoever owns the profiler should close the copy it no longer updates.Generated by Claude Code
