Improve application performance: profile .NET code and database calls

Profile and boost the performance of your .NET applications

ANTS Performance Profiler is an application profiler for .NET desktop, ASP.NET, and ASP.NET MVC applications:

  • Find performance bottlenecks fast by profiling both the .NET code and the data access layer
  • Get rich performance data, right-down to line-level timings and expensive database queries
  • Save time going round in circles diagnosing and debugging – let the profiler do the hard work for you
  • Explore unfamiliar code bases
  • NEW! Enhanced data access profiling: added support for profiling MySQL (or MariaDB) and PostgreSQL, so you can see queries run against those databases too

All the performance data you need in one single tool

  • From .NET code to database: View performance data for both your .NET code and database requests made by the .NET code. Profile database requests your application makes to any SQL Server, Oracle, MySQL (or MariaDB), and PostgreSQL database. This is ideal if you're using an ORM. More information about our database profiling support.
  • Understand web requests: View rich data about outbound http requests made by your application, including request and response header information. See all the information in the context of the .NET code which caused the request to run.
  • File I/O performance: Get comprehensive performance information on your application's disk activity.
  • View your most expensive code with the call tree

    Jump straight to the slowest activity

    The call tree shows performance data for every method and identifies the most expensive methods, database queries, and web requests.

  • View line-level timings

    Drill down to slow lines of code with line-level timings

    Profile C# or any other .NET code line by line, with precise timing data so you can find issues at a glance. Expensive lines of code are automatically highlighted for quick visual inspection.

  •  View your .NET code alongside database calls

    Look at your code's database interaction *

    Understand how your .NET code makes database queries and how those queries perform. ANTS Performance Profiler supports SQL Server and Oracle databases, whether local or remote.

  • See your application's outgoing http requests

    Capture outgoing web requests *

    Look at your application's outgoing http requests. Get data about the request and response headers, and see what .NET code caused them to run.

  • view the interactive timeline

    Immediate feedback on application performance

    Use the interactive timeline to check the CPU usage of your .NET or ASP.NET application and highlight problem areas to focus only on the data that matters.

  • Group methods by the HTTP calls that caused them

    Group methods by HTTP request *

    Code and database activity are grouped by HTTP request, exposing performance problems on specific web pages.

  • Profile C#5 async code

    Profile async code

    Understand the performance of C#5 async code. View activity in the context of the code you wrote, and see how work being done asynchronously is related to the async method which caused it to run.

  • Use integrated decompilation

    Decompile third-party code *

    Find bottlenecks in 3rd party components and framework assemblies using integrated decompilation, powered by .NET Reflector.

*Available in the professional edition only

"I don't know how I ever developed enterprise software without the ANTS profilers.
They have saved me weeks of effort and paid for themselves many times over."

Gerhard du Toit, KIT Limited

It's one thing to write software that compiles and "works". It's an entire other ball game to write software that performs and scales. ANTS Profiler can help you achieve that goal in a very big way. Red Gate's ANTS Performance Profiler 6 is easy to learn to use and the features are both robust and intuitive. I can confidently recommend this product to any professional developer who is interested is producing high-performance, scalable applications.
Peter Bromberg, Eggheadcafe

I have had a performance issue for a few days now and tried to pinpoint the cause using my brain and simple debugging tools. I made the purchase for ANTS and within 30 minutes had the issue identified and fixed!
Martin Altenstedt, InHill Software

Over the weekend, we rolled out a few speed improvements to the Stack Overflow engine. First, we did a quick pass with ANTS Profiler and identified a few places where redundant or unnecessary database queries slipped into our code. We like to do this every few months on common pages as a sanity check.

  • Practical Performance Profiling Microsoft MVP Jean-Philippe Gouigoux

    Jean-Philippe Gouigoux, Microsoft Certified Professional Developer and Technology Specialist, discusses performance profiling for .NET.

    This presentation is a must-see for anyone who is new to profiling, and is based on content from Jean-Philippe's new, free eBook Practical Performance Profiling.

    Jean-Philippe discusses the basics of profiling in developer-level detail, covers client and server-side profiling, and illustrates classic issues and patterns by demonstrating profiling on a real world application.

  • Failure to launch: Code, Upload, and Explode Microsoft MVP Jeremiah Peschka

    Before you load your valuable ASP.NET application into a rocket and aim for the cloud, let's do a sanity check. How do you handle bandwidth shortages that never let your app reach orbit? What happens if you need more speed to haul all these users up? If your uptime flames out, how can you easily plan for splashdown?

    Moving an ASP.NET application to the cloud may not be as difficult as putting someone on the moon, but there are a lot of places where something can go wrong. In this session you'll learn how to handle the limitations of a purely virtual environment, measure performance and identify bottlenecks, and deal with the changing availability of resources.
