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 HTTP request*

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

*Only available in Pro edition
