Performance Trend Analyzer
Software componentObservability & EvaluationObservability & Evaluationarc:PerformanceTrendAnalyzer
An analysis component that examines historical benchmark results over a window to classify accuracy, latency and cost trends and flag gradual drift that no single threshold violation reveals.
Responsibility. Detects gradual multi-week performance, cost and accuracy drift from benchmark history.
Also known as: Benchmark trend analysis, Latency creep detector

reads dependency
sends data to dynamic
triggers dynamic
Design guidance
- SHOULD recommend re-profiling when latency trends upward and cache/token review when cost trends upward, even without threshold breaches.
- SHOULD review info-level burn-rate trends weekly to catch degrading baselines (e.g., burn rate rising from 0.8 to 1.5).
- SHOULD alert on gradual degradation trends in latency, memory, cache size and error rate (e.g., memory leaks, connection pool exhaustion).
Quantitative guidance
As stated by the sources; verify before use.
- 30-day history showed latency +14.9% (1,876 to 2,156ms) and cost +18.2% ($0.011 to $0.013) while accuracy stayed stable (Ch7.3).
- Alert on > 10% hourly increase; memory growth > 10% of baseline flags a potential leak (Ref8.06, Ref8.07).
