Load Testing

Stress Test Example

#[test]
fn stress_test_10k_nodes() {
    let mut topology = NetworkTopology::new();

    let start = Instant::now();
    for i in 0..10_000 {
        topology.register_node(&format!("node-{}", i), &[0.5, 0.3, 0.2]);
    }
    let duration = start.elapsed();

    println!("10K nodes registered in {:?}", duration);
    assert!(duration < Duration::from_millis(500));
}

Concurrency Test Example

#[test]
fn concurrent_processing() {
    let rt = Runtime::new().unwrap();

    rt.block_on(async {
        let mut handles = vec![];

        for _ in 0..100 {
            handles.push(tokio::spawn(async {
                // Simulate 100 concurrent workers
                // Each processing 100 tasks
            }));
        }

        futures::future::join_all(handles).await;
    });
}

Interpreting Results

Latency Ranges

ns/iter Range	Grade	Performance
< 1,000	A+	Excellent (sub-microsecond)
1,000 - 10,000	A	Good (low microsecond)
10,000 - 100,000	B	Acceptable (tens of µs)
100,000 - 1,000,000	C	Needs work (hundreds of µs)
> 1,000,000	D	Critical (millisecond+)

Throughput Calculation

Throughput (ops/sec) = 1,000,000,000 / ns_per_iter

Example:
- 847 ns/iter → 1,180,637 ops/sec
- 12,450 ns/iter → 80,321 ops/sec
- 523,678 ns/iter → 1,909 ops/sec

Continuous Monitoring

Metrics to Track

Latency Percentiles
- P50 (median)
- P95, P99, P99.9 (tail latency)
Throughput
- Operations per second
- Tasks per second
- Transactions per second
Resource Usage
- CPU utilization
- Memory consumption
- Network bandwidth
Scalability
- Performance vs. node count
- Performance vs. transaction history
- Performance vs. pattern count

Performance Alerts

Set up alerts for:

Operations exceeding 1ms (critical)
Operations exceeding 100µs (warning)
Memory growth beyond expected bounds
Throughput degradation >10%
