The SpeedTrace Profiler consists of two components: Recorder and Analyzer.
The Recorder in SpeedTrace contains all the necessary parameters to start recording your application. It collects every function call, parameter, and return value from your dotNET application.
The Analyzer opens the trace result and either generates profiling (aggregations are made here) or profiling and tracing information.
SpeedTrace records your application retaining valuable data for when the need to bug-trap may arise.
Recorder (pre-recording process)
This section shows the features of the SpeedTrace Recorder. The Recorder is a fundamental part and first step that creates and stores the configuration of projects that will profile/trace your dot.NET applications.
Recorder options depend on the version of SpeedTrace you use.
SpeedTrace Pro:
SpeedTrace Basic:
Automatic detection of IIS version
Available in Basic and Pro versions. SpeedTrace detects the IIS version running in your system. This is useful since developers can focus on profiling their applications without having to worry about secondary IIS configurations in SpeedTrace.

Workspace management
Available in Basic and Pro versions. Now dot.Net developers can create and load new workspaces in order to have more control over projects. If you have the need to group certain projects according to a specific criterion, creating a workspace is the solution. You just have to select "Create new workspace" from the File menu and start to work in a fresh new space.

Exclusion of 2nd level of runtime calls
Available in Basic and Pro versions. When profiling dot.Net applications in search of performance or software errors, dot.Net, developers know how time-consuming runtime calls can be. Therefore, when developers profile their dot.Net applications, we should remind that SpeedTrace offers the special feature "Exclusion of 2nd level of runtime calls". This function provides only the first runtime call generated and incorporates the time consumed by subsequent runtime calls to it. The function is located in the Filters tab.

Trigger features
Available only in Pro version. Triggers (Start/Stop) indicate to SpeedTrace which method will start the profiling process and which will stop it. Setting triggers will allow you to analyze the specific behavior of methods within your dot.NET application, since you can set the number of calls a method can have before either starting or stopping the tracing process.

Recording filters
Available only in Pro version. Recording filters (Include/Exclude) indicate to SpeedTrace which methods must be recorded during the tracing process and which will be excluded. By setting recording filters, the scope of your trace is focused on special areas of your application. Recording and Post-processing filters now provide the same logic, allowing the user to perform complex filter combinations.

Callback API feature
Available only in Pro version. The Callback API is the programming interface of SpeedTrace Pro which allows developers to implement their own C or C++ code. It permits analysis and reaction to program states while tracing dot.NET applications in order to write log files, react to exceptions, set function parameters, and control test automation tools.

Save-to-disk option
Available in Basic and Pro versions. Save-to-disk writes the information obtained from the profiler into your hard drive. The Max. Trace File Size establishes the size of your trace file, while Write Cache Size sets the cache that will be progressily written. This feature is especially useful when a large amount of information is to be profiled.

Advanced options
Available only in Pro version. Advanced options provide certain features that advanced developers may take advantage of. Useful when profiling and tracing single threads in order to reduce the amount of data. Moreover, trace calls to unmanaged codes are necessary when time information of sequential calls (parent/children) is required.

Analyzer (post-recording process)
This section shows the features of the SpeedTrace Analyzer. The Analyzer is a fundamental tool designed to analyze traced/profiled dot.NET applications.
Analyzer options depend on the version of SpeedTrace you use.
SpeedTrace Pro:
SpeedTrace Basic:
Complete call stack trees
Available in Basic and Pro versions. This feature offers comprehensive dot.net profiling and tracing result information when respective triggers are activated. Parent method calls generated before triggers take effect are now captured and added to their related call stack, thus providing a complete history of calls. With this feature, dot.net developers are able to inspect parents of method calls for problems.

Find Exceptions a click away!
Available in Basic and Pro versions. SpeedTrace incorporates a feature helping developers to analyze their dot.Net applications fast and effectively while tracing. With this new feature, you will no longer be required to type the exceptions query string in the trace analyzer. Simply select "Find All Exceptions" from the Edit menu, and SpeedTrace will list every exception found, enabling you to just click and analyze!

Bug trapper
Available in Basic and Pro versions. The bug trapper or tracer allows you to continuously trace and examine your application's data flow to and from a function, and to reduce the amount of trace statements within your application. Bug trapper is useful when you have to identify development and integration problems while profiling and tracing system calls or third-party software. Moreover, it allows easy localization of bugs (programming errors, deadlocks, missing or wrong version of dlls)
