The powerful line level sampling profiler and the ultra-fast, low-overhead instrumentation profiler provide functionality to quickly pinpoint performance bottlenecks within the app.

The integrated focus feature simplifies the analysis of complex applications to a minimum.

In addition, the tool supports event tracing to maximize the user experience. File I/O activity, network activity and debug events can be captured. That way interesting app insights can be correlated with the timeline. Data context information can be added to investigate internals of apps beyond code level.

The built-in timeline functionality empowers the user to process interesting time ranges.

The integrated .NET memory profiler empowers the user to identify the root causes for memory issues and resource leaks. The memory profiler is fast with minimal overhead in regards to memory consumption and execution times.
Features:

• Memory overview (Managed Heap, Win32 Heap, Modules, Mapped Files, Stacks, etc.) to get the big picture.
• Tracking of memory and resource issues triggered from native code including the .NET runtime.
• Capture of Win32 allocations from any 3rd party code to investigate memory leaks from native code.
• GDI Resource Tracking to identity resource leaks (bitmaps, fonts etc.).
• Tracking of file mapping events which can contribute multiple gigabytes of memory usage for a single process with can cause sluggish performance.
• Analysis of crash (memory) dump files.

The built-in application event tracker captures interesting system and application event topics. For each traced event, the profiler provides timestamps and thread stacks information. For this purpose, the profiler can record both managed and native event triggers.
The tool can capture event activity with data context and error information, for instance:

• Network activity tracing: View WCF calls, Database queries, Web access with source and target endpoints, View SSL encrypted info.
• File I/O activity including named pipes: View .NET Remoting / WCF calls. View performed read/write operations with actual data read/written.
• Startup-Performance optimizer: Analyze root causes of JIT compilations, module relocations.
• Concurrency analyzer (threading events with trigger stacks) to pinpoint threading usage.

Unexpected exceptions can be another interesting source of problems that may not only affect the performance of your application but also its functionality.

.NET Runtime Analyzer highlights all exceptions which occur during the application execution. For each exception, it shows thread stacks on a line-level base to indicate the source line from which the problem was raised.

Furthermore, the built-in exception profiler allows the analysis of specific exception types or exception creation stacks to display frequencies and their distribution within the timeline.
