FAQPage Schema

How do I identify performance bottlenecks in my .NET application?▼

To identify performance bottlenecks in a .NET application, you analyze the codebase using a performance-profiler agent. This process detects latency issues like N+1 queries, missing async optimizations, and memory leaks.

What's the best way to analyze EF query performance?▼

The best way to analyze EF query performance is by profiling the query plans to detect inefficiencies. This targets Entity Framework-specific issues like N+1 queries to resolve application latency.

How do I run memory profiling and GC pressure analysis for .NET?▼

Memory profiling and GC pressure analysis for .NET requires utilizing dotnet-gcdump and dotnet-counters. These tools provide detailed diagnostics to identify memory leaks and optimize system resources.

Can I use BenchmarkDotNet for micro-benchmarking .NET async performance?▼

Yes, you can use BenchmarkDotNet for micro-benchmarking .NET async performance. The skill assists in setting up performance benchmarks specifically to measure and tune async bottlenecks.

Do I need dotnet-trace to perform async analysis on a .NET codebase?▼

Yes, you need dotnet-trace and other .NET profiling tools to perform detailed async analysis. These dependencies are required to execute traces and resolve async performance bottlenecks effectively.
