Performance requirements should be defined in quality gates:
# .f5/quality/gates-status.yaml
gates:
G2:
performance:
api_p95_response: "< 200ms"
database_p95_query: "< 50ms"
memory_usage: "< 80%"
Performance requirements should be traceable:
// NFR-PERF-001: API response time must be under 200ms at P95
export async function getUser(id: string): Promise<User> {
// implementation
}
