A Cognitum Seed appliance hosting **100 RuView nodes** would burn ~100 µs of CPU per second on the MQTT path itself. That's a 0.01% load floor. + +Memory: every primitive's FSM is a few dozen bytes of state. 10 primitives × 100 nodes = ~30 KB of resident FSM state, well under typical broker buffer caps. + +The user-supplied `--mqtt-rate-*` flags are the throttle, not the publisher. There's no need to optimise the hot path further for v0.7.0. + +## Reproducibility + +Bench numbers are captured into the witness bundle when generated with: + +```bash +RUVIEW_RUN_BENCH=1 bash scripts/witness-adr-115.sh +``` + +Output lands under `dist/witness-bundle-ADR115--/bench-results/` as both criterion's stdout log and the HTML report tarball. + +## Cross-platform note + +These measurements are from a single laptop. Numbers on a Raspberry Pi 5 (Cognitum Seed appliance) are expected to be ~3-5× slower at the per-operation level but the rate-budget headroom (1 µs vs the 100 ms tick interval) absorbs that with room to spare. diff --git a/v2/crates/wifi-densepose-sensing-server/examples/mqtt_publisher.rs b/v2/crates/wifi-densepose-sensing-server/examples/mqtt_publisher.rs index a31242bc..1e81c5f9 100644 --- a/v2/crates/wifi-densepose-sensing-server/examples/mqtt_publisher.rs +++ b/v2/crates/wifi-densepose-sensing-server/examples/mqtt_publisher.rs @@ -20,15 +20,35 @@ //! the active edit surface of the parallel ADR-110 agent — see //!
