dev-browser benchmarks
Measures the numbers from docs/design-decisions.md §8 against an isolated
DEV_BROWSER_HOME temp dir and a warm headless daemon. Everything is cleaned up at
the end (daemon stopped, temp home removed), also on error.
bun run bench/run.ts [--check] [--bin PATH] [--runs N]
- Uses
dist/dev-browserwhen it exists (bun run build), elsebun run src/cli/main.ts(slower cold start and per-call client time).--binoverrides. The chosen binary is printed first;--bin devforces thebun runpath. --runs Nis the sample count per item (default 15); the table shows medians.--checkexits 1 if any measured item is over its target. Items that are skipped because the API is not implemented yet count as pass.

Fixtures live in bench/fixtures/ (small.ts, serp.ts) and are served by a
local Bun.serve on 127.0.0.1. bench/fixtures/fixtures.test.ts pins their
size (bun test bench/fixtures).
In-process micro-harness
bun run bench/inproc.ts [--runs N]
Calls runScript from src/daemon/run.ts directly with a fake emit and a
BrowserManager: no socket, no client process. Compare its 1+1 median with
the 1+1 row of bench/run.ts to see how much of the end-to-end time is the
client (process start + socket round trip) vs the daemon.
CI
CI runs bun run build && bun run bench/run.ts --check on Linux (headless
Chrome, --no-sandbox is applied automatically when the sandbox is
unavailable). Medians are noisy on shared runners; bump --runs rather than
the targets if it flakes.
