Trigger detection exceeded 5ms target: ${detectionTime.toFix

Error message

Trigger detection exceeded 5ms target: ${detectionTime.toFixed(2)}ms

What it means

Performance warning in WorkerDispatch.detectTriggers(): regex scanning of the input text for trigger patterns exceeded the 5ms budget. Detection still returns correct results; the warning marks the trigger-pattern set or input as a latency hotspot.

Solutions

1. Optimize the trigger detection hot path: precompile regexes, index triggers, and avoid repeated parsing.
2. Cache trigger evaluation results where inputs are unchanged.
3. Profile detection to locate the slow check and move non-critical work off the 5ms path.

When it happens

Trigger: Trigger-detection pass over the event stream takes longer than the 5ms budget; triggered by oversized event batches, regex-heavy matchers, or GC pauses on the dispatch hot path.

Common situations: See trigger scenarios.
