Task execution time degradation impacts user experience

Task execution time p95 exceeds 60 seconds when normal is <30s. Prolonged task duration indicates resource contention, inefficient code, or external dependency issues.

Monitor task execution time p95 percentile. Alert if >60s when baseline is <30s. Identify slow tasks using full-text search on task results. Review resource allocation (CPU, memory) for workers. Check external dependencies (databases, APIs) for latency. Optimize problematic task code identified in failure pattern analysis.
