The benchmark runs in CI, and fails when the jank metric is missing
Item 5 of the queue: .github/workflows/benchmark.yml measures on an API 35 emulator (reactivecircus/android-emulator-runner, google_apis, x86_64, SwiftShader), on demand and every Monday. Not on pull requests: a run is minutes of measurement behind twenty of booting an emulator, and the gate is meant to answer in one or two. It installs both APKs and instruments directly instead of using connectedBenchmarkAndroidTest, because that task installs the app itself - which undoes the compile reset that makes the measurement a never-run baseline. tools/benchmark-report.py turns the JSON into two tables, keeping frameCount (a length) apart from frameDurationCpuMs and frameOverrunMs (speeds), and --require-frame-duration fails the job when the second table would be empty: the metric is the reason the job exists. Driving the workflow's own script against the phone first paid for itself three times. It found that cmd package compile --reset needs adbd as root - a user build refuses it with SecurityException, so the workflow now does adb root first (google_apis allows it) instead of silently measuring a compiled app. It produced the second run of the 20 000-file open (16 frames median, 32 max) and the first numbers for scroll, search and cold start at that size: search costs 319 frames, which is now the biggest number in the file. And it showed the phone reporting frameDurationCpuMs and frameOverrunMs after all, so PERFORMANCE.md's 'this phone reports counts only' was a property of those earlier runs, not of the handset - corrected, with the numbers.

|

# * **It is a second opinion.** The numbers in docs/PERFORMANCE.md come from one handset; an emulator run
|

### The whole suite at 20 000 files, twice

The script that the CI workflow runs was also run against the same 20 000-file fixture — it is
|

device-agnostic apart from the emulator runner — which gave a second, independent run of the open
|
||||
benchmark and, for the first time, the other three at that size:

Two things in it are worth keeping:

|
||||
* **The batching result holds in a second run.** The table above has 12 median / 48 max from one run; this
|
||||
one has 16 median / 32 max on a build that also carries the M16 picker. That is the same number within
|
||||
the noise, and the 598-frame stall has not come back.
|
||||
* **Search is the next outlier.** 319 frames is about five seconds from the query to `file-99.txt`,
|

against 38–39 frames at 1 000 files: twenty times the entries for eight times the frames, so sublinear —

but still long enough to notice, and the per-frame numbers say drawing is not the reason (P90 11.5 ms).

Handing twenty thousand rows to a list in one go is; that is where a "large folder" pass would start.

`coldStart`'s 599 ms and 162 frames of scrolling are recorded here as the baseline those two get

### The same thing in CI
|
||||
|
||||
`.github/workflows/benchmark.yml` runs those four commands on an emulator
|
||||
(`reactivecircus/android-emulator-runner`, API 35, `google_apis`, x86_64, SwiftShader), on demand and every
|
||||
Monday morning. It is deliberately not part of the pull-request gate: a run is minutes of measurement behind
|
||||
twenty minutes of booting an emulator, and the gate is meant to answer in one or two minutes.
|
||||
|
||||
Two details make the numbers meaningful rather than merely present:
|
||||
|
||||
* The app is installed and `cmd package compile --reset` **before** the instrumentation starts, and the run
|
||||
is driven with `am instrument` rather than `connectedBenchmarkAndroidTest` — the Gradle task installs the
|
||||
app itself, which would undo that reset and quietly measure a compiled app.
|
||||
* `tools/benchmark-report.py --require-frame-duration` turns the results into a table on the run's page and
|
||||
**fails the job** when `frameDurationCpuMs` is missing. That metric is the reason the job exists; a run
|
||||
without it is not a green run with a footnote.
|
||||
|
||||
The emulator's milliseconds are not a phone's — software rendering, a different CPU, no thermal limits — so
|
||||
they are read as shape and trend (which benchmark is slow relative to the others, whether a change moved it),
|
||||
not as an absolute.

What the interaction numbers still need is a device that reports frame durations — an emulator or any

numbers are one handset's, the emulator's are software-rendered, and neither is a claim about a mid-range

device. The install side is solved: `CompilationMode.Ignore()` plus installing from the host means a run
