.NET code profiler.
ANTS Performance Profiler offers detailed performance data for .NET desktop, web, and service applications. It helps developers pinpoint slow spots in code, databases, web requests, and file input/output with line-level timings and integrated decompilation. It supports multiple databases and async code, improving troubleshooting efficiency.

Comprehensive .NET profiling

Profiles .NET executables, ASP.NET applications, Windows services, and other .NET-based apps with line-level timing and sampling modes to identify slow methods and code segments.

Database query analysis

Profiles SQL Server, Oracle, MySQL (including MariaDB), and PostgreSQL queries with SQL statement timings and execution plans, showing how .NET code triggers database operations.

Web request diagnostics

Captures outgoing HTTP requests including headers and correlates them to originating .NET code for deep insight into web interactions affecting performance.

File I/O performance monitoring

Measures disk activity with detailed read and write speeds for individual files, helping uncover file system bottlenecks within your application.

Async code support

Enables profiling of C# async methods, showing how asynchronous activities relate to the triggering code for accurate performance analysis.

Third-party code decompilation

Integrated decompilation powered by .NET Reflector allows analysis of framework and external component methods alongside your own code.

Interactive timeline and call tree

Provides an interactive CPU usage timeline and call tree that highlights the most resource-intensive methods, queries, and web requests for quick focus.

Grouping by HTTP request

Organizes code and database activity by HTTP request to expose bottlenecks affecting specific web pages or services helping pinpoint location of performance issues.

Easy integration and workflows

Compatible with Visual Studio 2010 and later, allowing in-IDE launch, attaching to running processes without restarts, and saving/exporting profiling results for collaboration.
