Les enseignants ont besoin de moyennes à jour immédiatement après la publication ou modification des notes, sans attendre un batch nocturne. Le système recalcule via Domain Events synchrones : statistiques d'évaluation (min/max/moyenne/médiane), moyennes matières pondérées (normalisation /20), et moyenne générale par élève. Les résultats sont stockés dans des tables dénormalisées avec cache Redis (TTL 5 min). Trois endpoints API exposent les données avec contrôle d'accès par rôle. Une commande console permet le backfill des données historiques au déploiement.

# Subagent 4B: Performance NFR Assessment
|
|
|
|
## SUBAGENT CONTEXT
|
|
|
|
This is an **isolated subagent** running in parallel with other NFR domain assessments.
|
|
|
|
**Your task:** Assess PERFORMANCE NFR domain only.

|
## SUBAGENT TASK
|
|
|
|
### 1. Performance Assessment Categories
|
|
|
|
**A) Response Times:**
|
|
|
|
- API response times (<200ms target)
|
|
- Page load times (<2s target)
|
|
- Time to interactive (<3s target)
|
|
|
|
**B) Throughput:**
|
|
|
|
- Requests per second capacity
|
|
- Concurrent user support
|
|
- Database query performance
|
|
|
|
**C) Resource Usage:**
|
|
|
|
- Memory consumption
|
|
- CPU utilization
|
|
- Database connection pooling
|
|
|
|
**D) Optimization:**
|
|
|
|
- Caching strategies
|
|
- CDN usage
|
|
- Code splitting/lazy loading
|
|
- Database indexing
