Covers the end-to-end request lifecycle, a comparison table of common middleware and their performance impacts, common mistakes (e.g., placing authentication before static files), and a benchmarking methodology using tools like k6, Bombardier, dotnet-counters, and dotnet-trace. Includes troubleshooting tips and best practices for building faster, more scalable APIs. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### Why does putting authentication middleware before static files hurt performance in ASP.NET Core? Requests for static assets unnecessarily pass through authentication middleware when it is registered earlier in the pipeline, adding processing overhead even though those files typically don't require authentication. Registering static file middleware before authentication and authorization lets static assets be served immediately without extra processing, improving throughput for those requests. _Developers tuning middleware order can use daily.dev to compare ASP.NET Core performance patterns._ ### What order should UseAuthentication and UseAuthorization be registered in ASP.NET Core? UseAuthentication() must be registered before UseAuthorization() and before endpoint mapping. Reversing this order causes authorization checks to run before a user has been authenticated, which leads to authentication failures and incorrect permission evaluation. _Anyone debugging ASP.NET Core auth pipelines can track ordering gotchas like this on daily.dev._ ### What tools can I use to benchmark ASP.NET Core middleware performance? Useful tools include k6 and Bombardier for load generation, plus dotnet-counters and dotnet-trace for collecting CPU, memory, and latency metrics. A sound methodology keeps the .NET SDK, ASP.NET Core version, hardware, hosting configuration, and application settings identical across runs, then measures average response time, P95/P99 latency, requests per second, CPU utilization, memory consumption, and error rate under production-like workloads. _Teams building a repeatable benchmarking process can find comparisons of tools like k6 on daily.dev._ ## Similar posts on daily.dev -
