Chased the "stream frame p95 = 60ms with ZERO longtasks" mystery to its actual cause: the default stream chunk had no paragraph breaks, so it grew into one giant ~22KB block that re-rendered fully every flush — defeating the block memoization real streaming relies on. Plain text = 21ms; realistic chunk with `\n\n` breaks (blocks settle, only the tail re-renders) = 23ms. Fixed the default chunk to model real LLM output; a break-less `--chunk` remains available as a single-block worst-case stress. Also hardened the isolated instance so measurements reflect real cost: - Wait for the gateway socket to actually connect before measuring (a booting/ absent backend's reconnect backoff churns the main thread). Exposed via a new __PERF_DRIVE__.connected() probe reading $gateway.connectionState. - Focus emulation + anti-throttle/occlusion flags so a backgrounded perf window isn't frame-throttled (no OS focus stealing). - Generation-guarded the rAF frame recorder so repeated runs don't leave overlapping recorders polluting frame intervals. Baseline re-captured as the median of 5 --spawn runs (darwin-arm64); all three CI scenarios now green and stable. Absolute values are dev-build (noted in _meta) — regression guards, not shipped numbers. |
