Performance Testing and Load Testing ASP.NET Core APIs — ShopNest
Article 57 of 75 · Module 7: Testing · ShopNest Production API Optimization
Target keyword: load testing asp.net core · Read time: ~32 min · .NET: 8 / 9 · Project: ShopNest Production API Optimization

Introduction

Before ShopNest flash sales, know your API limits — k6 load tests and BenchmarkDotNet micro-benchmarks reveal DB and CPU bottlenecks before customers do.

After this article you will

  • Run k6 load scripts against ShopNest API
  • Use BenchmarkDotNet for hot path code
  • Profile with dotnet-counters and dotnet-trace
  • Interpret latency percentiles (p95, p99)
  • Optimize based on profiling evidence

Prerequisites

Concept deep-dive

// k6 script — shopnest-load.js
import http from 'k6/http';
import { check, sleep } from 'k6';

export const options = {
  stages: [
    { duration: '1m', target: 50 },
    { duration: '3m', target: 200 },
    { duration: '1m', target: 0 },
  ],
  thresholds: { http_req_duration: ['p(95)<500'] },
};

export default function () {
  const res = http.get('https://api.shopnest.local/api/v1/products?page=1');
  check(res, { 'status 200': (r) => r.status === 200 });
  sleep(1);
}
// BenchmarkDotNet
[MemoryDiagnoser]
public class OrderTotalBenchmark
{
    [Benchmark]
    public decimal CalculateTotal() => OrderCalculator.Compute(_sampleLines);
}

Metrics: ASP.NET Core exposes requests/sec, active connections. Watch SQL CPU and connection pool exhaustion under load.

Hands-on — ShopNest Production API Optimization

  1. k6 run against local ShopNest product list API.
  2. Baseline p95 latency; add Redis cache; re-run and compare.
  3. dotnet-counters monitor System.Runtime and Microsoft.AspNetCore.Hosting.
  4. Document bottleneck (missing index vs no cache) and fix.

Common errors & best practices

  • Load testing production without approval — use staging.
  • Optimizing without measuring — guesswork wastes time.
  • Ignoring connection pool limits under high concurrency.

Interview questions

Q: p95 latency?
A: 95% of requests faster than this value — SLA metric.

Q: k6 vs JMeter?
A: k6 scriptable in JS, developer-friendly; JMeter GUI-heavy.

Q: BenchmarkDotNet purpose?
A: Micro-benchmark C# methods with statistical rigor.

Summary

  • Load test before major ShopNest launches
  • k6 stages simulate ramp-up traffic realistically
  • Profile first — cache and indexes fix most API slowness
  • p95/p99 matter more than average latency

Next: Test-Driven Development

FAQ

Artillery alternative?

YAML-based load tests — similar to k6 for HTTP.

Load test auth endpoints?

Use k6 setup() to fetch JWT once, reuse in VUs.
