# iOS run 2026-10-25 on EAS (/docs/bench/ios-2026-10-25) The run behind the 2026-10-25 iOS dataset on the [comparison page](/docs/bench/comparison). Everything below comes from the four workers' artifacts, merged into one report; nothing was measured on a developer machine. ## Headline [#headline] warden ran the warm 8-test suite in 86.30 s. That is 1.56× faster than Argent (134.32 s), 1.06× faster than agent-device (91.61 s, one failed test) and 1.54× faster than tester.army (132.52 s). Per step, warden's median is 85 ms against 321 ms (Argent, 3.8×), 471 ms (agent-device, 5.5×) and 481 ms (tester.army, 5.7×). Its host CPU is 2.97 CPU-s per rep against 4.13 (Argent, 1.4×), 11.18 (agent-device, 3.8×) and 17.74 (tester.army, 6.0×). ## How it was run [#how-it-was-run] | | | | ----------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | | Workflow | `apps/example/.eas/workflows/bench-baseline.yml`, EAS Workflows run [`01a1756a-abaa-7940-95ba-336e7d9160e9`](https://expo.dev/accounts/delacour/projects/warden/workflows/01a1756a-abaa-7940-95ba-336e7d9160e9), inputs `runs=5`, `frameworks=warden,argent,agent-device,tester-army`, `max_minutes=55` | | Code | warden commit `51bb4cee` (branch `develop`, warden 0.3.1), every suite under `packages/e2e-bench/suites/` | | Workers | One EAS `macos-large` worker per framework, four in all. VM template `macos-tahoe-26.5-xcode-26.6`: VirtualMac2,1, Apple M4 Pro (Virtual), 10 cores, 40 GB, macOS 26.5.2 (25F84), Xcode 26.6 (17F113) | | Simulator | Each worker claims its own headless simulator with `warden claim ios --headless` (iPhone 17, iOS 26.5, named `warden-iphone-17-1`), created fresh for the job and shut down at the end. Nothing one framework leaves behind can reach another | | App | The same build on every worker: `nz.co.delacour.warden.example`, EAS `bench` profile (Release, simulator), sha256 `c283eae41c7a`, 101.1 MB, reused by fingerprint (`build_ios` skipped), installed with `simctl install` before the bench | | Runs | 5 runs of the 8-test suite per framework. Run 1 is cold; warm numbers are the median of runs 2 to 5. `retries=0`, fresh app launch per test, `caffeinate -dims` held | | Before the bench | `bun install`, `warden-simd` built from source (Swift release), the framework installed (`bun add -g @swmansion/argent@0.30.1` / `agent-device@0.21.31`; tester.army's `e2e` 0.20.0 comes with `bun install`, Node 22.23.1), then the job waits for the 1-minute load average to drop under the core count and records a 60 s idle control of the simulator with the app in the foreground | | Deep-link sheet | iOS shows "Open in …?" for the first custom-scheme link after a boot and never again, so the harness opens one link and answers the sheet before every framework's prepare. No suite handles the sheet itself | | Hard stop | A watchdog stops the bench at `max_minutes`; it did not fire on any worker (the longest job, agent-device, ran 28 min) | | Isolation per framework | Helpers of every framework stopped, driver apps uninstalled before the run (cold cost measured), residue listed after teardown | | Sampling | Host and simulator processes sampled every 500 ms from `ps`; the CPU headline is CPU-seconds of the framework's own process tree during the timed run, warm median | | Evidence on exit | Each job screenshots the simulator and lists the apps still running, releases the lease even when a step failed, and uploads an `eas-ios-` artifact | | Versions | bun 1.3.14, warden 0.3.1, Argent 0.30.1, agent-device 0.21.31, tester.army e2e 0.20.0 (bundled agent-device 0.21.25), Node 22.23.1 | Hosted workers idle hotter than a Mac and share their host, so these numbers compare only with other `macos-large` runs, never with runs on other hardware. agent-device dropped one test in run 1 (`sign-in/field-errors`: its `fill` read back an empty field after typing), so its pass rate is 97.5% and, by the fairness rules, it cannot be called fastest even where a per-test median is lower. Its other 39 tests passed. ## Results [#results] ### Summary [#summary] | Framework | Status | Version | Suite median (warm) | p95 | Ratio | Cold rep 1 | Cold-start cost | Prepare | Teardown | Overhead | Pass rate | Flake | Residue | Footprint (LOC / deps) | | ------------ | ------ | ----------------------- | ------------------- | -------- | ----- | ---------- | --------------------------------- | ------- | -------- | -------- | --------- | ----- | ----------------------- | ---------------------- | | warden | ok | bun 1.3.14 + warden-e2e | **86.30 s** | 86.71 s | 1.00× | 71.98 s | none (rep 1 not slower, -13.72 s) | 596 ms | 72 ms | 67 ms | 100% | 0% | 0 proc / 0 app / 0 path | 379 LOC / 0 B | | argent | ok | 0.30.1 | 134.32 s | 134.65 s | 1.56× | 133.61 s | 1.01 s | 1.72 s | 293 ms | 163 ms | 100% | 0% | 0 proc / 0 app / 1 path | 161 LOC / 0 B | | agent-device | ok | agent-device 0.21.31 | 91.61 s ✗ | 91.70 s | 1.06× | 87.46 s | 12.23 s | 16.37 s | 315 ms | 213 ms | 97.5% | 2.5% | 0 proc / 1 app / 1 path | 158 LOC / 0 B | | tester-army | ok | e2e 0.20.0 | 132.52 s | 132.89 s | 1.54× | 150.63 s | 18.11 s | 0 ms | 495 ms | 2.24 s | 100% | 0% | 0 proc / 1 app / 1 path | 307 LOC / 0 B | ### Per-test medians (ms) [#per-test-medians-ms] | Test | warden | argent | agent-device | tester-army | | ---------------------------------------------------------- | ----------------- | ------------- | ----------------- | ------------- | | onboarding steps through to sign-in | **2929 (1.00×)** | 8301 (2.83×) | 3830 (1.31×) | 5964 (2.04×) | | invalid email and short password show field errors | **16054 (1.00×)** | 18221 (1.13×) | 16579 ✗ (1.03×) | 21119 (1.32×) | | a locked account shows the form alert | 10096 (1.04×) | 14442 (1.49×) | **9673 (1.00×)** | 12914 (1.34×) | | valid credentials land on todos | **9788 (1.00×)** | 15416 (1.58×) | **9784 (1.00×)** | 14850 (1.52×) | | add, complete and filter todos | **14494 (1.00×)** | 21110 (1.46×) | 15470 (1.07×) | 21230 (1.46×) | | open a todo, mark it done, then delete it | **11089 (1.00×)** | 19105 (1.72×) | 12422 (1.12×) | 18121 (1.63×) | | deep link opens a todo by id | 10656 (1.02×) | 17811 (1.70×) | **10483 (1.00×)** | 18094 (1.73×) | | settings shows the account, toggles switches and signs out | **10945 (1.00×)** | 19616 (1.79×) | 13136 (1.20×) | 18075 (1.65×) | ### Per-step latency [#per-step-latency] | Framework | Steps | Median | p95 | Max | | ------------ | ----- | ------ | ------ | ------ | | warden | 504 | 85 ms | 3.63 s | 4.98 s | | argent | 1192 | 321 ms | 1.82 s | 2.82 s | | agent-device | 632 | 471 ms | 1.62 s | 1.89 s | | tester-army | 592 | 481 ms | 3.21 s | 4.01 s | #### Where step time goes [#where-step-time-goes] Step scopes differ per tool: warden's one `fill` step spans the focus tap, select-all, typing and read-back confirm, argent reports a separate `idle` step and `into …`, agent-device reports `fill` and `type` separately, and tester.army reports locator steps.

RSS is a per-process sum, so shared framework pages are counted once per process: compare the numbers across frameworks, not against physical memory. `CPU-s / rep` (the CPU headline) is the CPU time of the timed run only, median over the warm reps (over every rep, cold included, when a framework has no warm rep, as with `--runs 1`), from per-process deltas of `ps time`; the other columns are whole-framework (prepare, every rep, the per-rep housekeeping and teardown), so their averages move with suite length. `CPU avg` / `CPU peak` are `ps %cpu`, a decaying average on macOS, kept for comparison with older runs. Android `sim` has no CPU-seconds (`top` only). CPU-seconds undercount: CPU a process uses after the last 500 ms tick, and processes living between ticks, are only recovered for children the bench ran itself (their rusage at exit); daemons and processes a framework spawns and never waits for are not, so frameworks that fan out to many short-lived tools read low. An exit charge is booked to its root's group, so in the per-group split the unseen CPU of a descendant of another group (a `bun test` under a `warden` root) shows under the root. procps (Linux) `ps time` has 1 s resolution. #### Host by process group [#host-by-process-group] | Framework | Group | CPU-s (whole) | RSS avg | RSS peak | | ------------ | ----------- | ------------- | -------- | -------- | | warden | bun-test | 6.21 s | 89.6 MB | 102.2 MB | | warden | warden-simd | 8.61 s | 56.2 MB | 56.7 MB | | warden | warden-cli | 0.11 s | 131.6 KB | 78.8 MB | | warden | other | 0.43 s | 0 B | 0 B | | argent | other | 21.38 s | 181.4 MB | 236.7 MB | | agent-device | other | 78.73 s | 711.9 MB | 2.4 GB | | tester-army | other | 110.24 s | 598.2 MB | 2.5 GB | `bun-test` the spec process, `warden-simd` the resident iOS helper, `warden-cli` the `warden` commands the bench spawned, `adb` / `emulator` the Android tools, `other` the rest (another framework's runner, `xcrun`, java). Each group's RSS average counts 0 for ticks without a process, so the groups add up to the host. ### Where the CPU goes [#where-the-cpu-goes] #### warden [#warden] | Process | Scope | CPU-s | Share |

One table per framework, from the warm-median rep's timed run (the rep whose host CPU-seconds is the lower median). Rows are processes grouped by label (top 12 per scope, the rest in `other`); `host` is the framework's own process tree, `sim` the simulator's `launchd_sim` tree (iOS only). `Share` is of the scope's CPU-seconds. `RSS` is the label's summed RSS per 500 ms tick (0 where it had no process). `Spawns` counts distinct pids a tick saw: a process that lives between two ticks is only seen through the `(exit charge)` rows (CPU of a child the bench ran, booked at its exit), so many short-lived `xcrun simctl` calls read low in `Spawns` and in CPU. ### Residue [#residue] * **warden:** none * **argent:** paths: /Users/expo/.argent (328.0 KB) * **agent-device:** driver apps: com.callstack.agentdevice.runner.uitests.xctrunner; paths: /Users/expo/.agent-device-bench/agent-device (2.9 MB) * **tester-army:** driver apps: com.callstack.agentdevice.runner.uitests.xctrunner; paths: /Users/expo/.agent-device-bench/tester-army (4.9 MB) ### Unsupported / failed [#unsupported--failed] None. ## Change since the previous run [#change-since-the-previous-run] The previous four-framework run on the same workflow and worker class, [`01a172f5`](https://expo.dev/accounts/delacour/projects/warden/workflows/01a172f5-fdee-7992-b66c-a2173338eb32) at warden 0.1.1, is replaced by this one. Between them warden's resident helper took over launch, terminate and open-URL from `simctl`, reads fewer trees after an input, links idb 1.7.7 with its single-pass frame decoder, and boots simulators slim. The other frameworks are at the same versions on both runs. | warden, warm | 0.1.1 (`01a172f5`) | 0.3.1 (`01a1756a`) | Delta | | ------------------------ | ------------------ | ------------------ | ---------------- | | Suite median | 97.04 s | 86.30 s | -10.74 s (-11 %) | | Step median | 170 ms | 85 ms | -85 ms (-50 %) | | Host CPU-seconds per rep | 9.12 s | 2.97 s | -6.15 s (-67 %) | | of which `warden-simd` | 7.03 s | 1.76 s | -5.27 s (-75 %) | | Host RSS peak | 184.9 MB | 158.6 MB | -26.3 MB | | Ratio to Argent | 1.36× | 1.56× | | | Ratio to agent-device | 0.95× | 1.06× | | | Ratio to tester.army | 1.36× | 1.54× | | | Pass rate / flakes | 100 % / 0 | 100 % / 0 | | Argent, agent-device and tester.army moved by less than 2 % between the two runs (131.81 → 134.32 s, 91.77 → 91.61 s, 132.34 → 132.52 s), which is the worker-to-worker noise to read every ratio against. ## Artifacts [#artifacts] Each worker uploaded its results directory as one archive. The viewable files are copied here; the archives hold everything, including the per-rep `resources.ndjson` ticks and the 60 s idle control. To re-render one: download the archive, `tar -xzf` it, then `bun run bench report Users/expo/bench-results` from the warden repo. ### Merged run [#merged-run] The four results merged into one run, `bench-2026-10-25-ios-eas`, ratios recomputed across the four: [report.html](/bench/ios-2026-10-25/merged/report.html), [report.md](/bench/ios-2026-10-25/merged/report.md), [bench-results.json](/bench/ios-2026-10-25/merged/bench-results.json), [summary.json](/bench/ios-2026-10-25/merged/summary.json) (the comparison page's dataset). ### warden [#warden-1] Worker job `bench_warden`, bun 1.3.14 + warden-e2e (this commit).
