3 people	081d6f95ef	perf(track): avoid per-frame allocations and list lookups in tracker (#23523) ... Two small per-object-per-frame improvements in the tracker hot path (match_and_update), both bit-identical: - get_stationary_threshold returned a freshly constructed StationaryThresholds (a dataclass plus a list) on every call for any label not in the three known lists - i.e. for common labels like person/dog. The default thresholds are constant and never mutated, so return a shared module-level singleton, as the other three cases already do. - untracked_object_boxes membership used `box not in [list of boxes]` (O(n)); build a set of box tuples for O(1) membership. Boxes are hashable as tuples and output is unchanged. get_stationary_threshold appeared in a live py-spy --gil profile of a camera process_frames worker. Adds tests for the threshold lookups.

3 people	a2b46f5d84	perf(util): cut redundant work in per-frame detection consolidation (#23522) ... video/detect.py runs these for every frame: - get_cluster_candidates: used_boxes was a list with `in` membership tests inside the nested loop (O(n) per check). It is only ever membership-tested, so switching it to a set (O(1)) leaves output unchanged. - get_consolidated_object_detections: area(current_box) was recomputed on every inner-loop iteration though it is loop-invariant; hoist it to one call per outer detection. Both are bit-identical (verified against the previous implementations over randomized inputs). Measured in the release image, get_cluster_candidates on a frame of 30 detection boxes: 59.2 us -> 42.1 us (1.4x); the gain scales with the number of boxes per frame. Adds a partition-invariant test (every box index lands in exactly one cluster). Co-authored-by: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-06-23 15:23:18 -06:00
3 people	d982b3a782	perf(util): use monotonic clock and bounded deque in EventsPerSecond (#23520) ... * perf(util): use monotonic clock and bounded deque in EventsPerSecond EventsPerSecond is updated on every captured frame, every detection and every processed frame across all cameras and detectors. The previous implementation derived timestamps from datetime.now().timestamp() (wall clock), so an NTP or manual clock adjustment could skew the rolling-window expiry; it also stored timestamps in a list and expired them with del self._timestamps[0] (O(n) per removal) plus a periodic slice-copy to cap growth. Switch to time.monotonic() for the interval math (correct by construction and immune to wall-clock jumps) and a collections.deque(maxlen=...) so expiry is O(1) (popleft) and retention is bounded automatically. This mirrors the deque-based expiry already used in video/ffmpeg.py and watchdog.py. Observable output is unchanged. Adds frigate/test/test_builtin.py covering rate calculation, window expiry and the memory bound. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * test: drop test_timestamps_are_memory_bounded It only asserted that deque(maxlen=) caps length, which is stdlib behavior rather than something this change needs to verify.
