The AISDP declares the system’s performance characteristics, including latency at the p50, p95, and p99 percentiles and throughput capacity. These declarations are compliance commitments that must hold under production load. Load testing verifies that the deployed system meets these commitments under realistic traffic conditions.

Locust and k6 are modern load testing tools that generate configurable traffic patterns and report percentile latency distributions. Load tests should simulate the expected request rate, request size distribution, and concurrent user count. The tests are run against the staging environment before every production deployment, and periodically against production during off-peak windows to confirm that the system’s performance characteristics have not degraded.

The test results, including the exact test configuration and load profile, are retained as Module 5 evidence. If the load test reveals that the system’s latency exceeds the declared threshold at the expected production load, the deployment is blocked until the performance issue is resolved or the AISDP’s performance declarations are updated through the governance process.

Key outputs

• Load test configuration simulating production traffic patterns
• Percentile latency measurements (p50, p95, p99) under load
• Throughput capacity verification
• Module 5 and Module 3 AISDP evidence
