Struggling to find the performance bottlenecks for your software written in multiple languages?
Do you want to view a real-time call stack as your application executes?
Do you want to automate your performance profiling?
Do you want to post your profiling results on your company intranet in HTML or XML?
If that sounds like you, we’ve got a software profiling tool for you.
Performance profiling with Performance Validator.
Performance Validator is a performance profiler for use by software developers and software quality assurance testers using .Net, .Net Core (C#, VB.Net, etc) and native language compilers (C, C++, Delphi, VB6, Fortran etc.).
Use Performance Validator to:
The call stack view displays the current call stack for the selected thread.
This view is useful for getting a quick insight into where the application is currently executing.
Threads can be named by the program under test using SetThreadDescription(), the thread name exception, or named explicitly using the user interface.
The Statistics view displays performance data for all functions that have been executed.
You can sort the data by any of the displayed criteria, allowing you to find the busiest functions, the slowest functions, and the functions taking all the time, etc.
When a function is selected in the left-hand pane, the source code for that function is displayed in the right-hand pane, with related statistics for the performance node displayed above the source code.
The relations view allows you to explore the relationship between a function, the functions that call it, and the functions that it calls.
When a function is selected in one of the left-hand panes, the source code for that function is displayed in the right-hand pane, with related statistics for the performance node displayed above the source code. In addition, the relations panes for the callers and callees of the functions are also populated, allowing you to see which functions call which other functions.
A Back button allows you to retrace your steps when analysing the data.
The Call Tree view displays a collapsible performance call tree calculated from the profiling data.
The call tree can be filtered to remove nodes that contribute less than a specified threshold value, allowing you to ignore functions that contribute little profiling time.
The colour coding allows at-a-glance viewing of the performance contribution of each function in the performance call tree.
The Call Graph view displays a collapsible performance call graph calculated from the profiling data.
This view is similar to the Call Tree, except that the Call Graph is the minimal set of all functions shown in the Call Tree.
The call graph can be filtered to remove nodes that contribute less than a specified threshold value, allowing you to ignore functions that contribute little profiling time.
The colour coding allows at-a-glance viewing of the performance contribution of each function in the performance call graph.
Sometimes the best way to dig into a problem is to run queries on the data rather than look at the various data displays. That’s what the Analysis view is for. The Analysis view allows you to slice and dice the profiling data using various queries.
The results of each query can be restricted to a small subset of the results if required, allowing “show 10 most timing consuming functions” type of query.
The results are shown as a colour-coded performance hotspot graph that can be expanded and collapsed as desired.
The line times view displays line timing statistics for each line in each source file of the application.
Line timing is best applied to one function at a time – using the Line Timing Filters.
The best workflow is to identify a function using function profiling, and then select that function for line timing to work out which parts of that function are slow.
The diagnostic view informs you of any information that you need to know which may affect the performance of Performance Validator.
You don’t need to modify your application, recompile your software or relink your application.
Just launch your application from Performance Validator and start profiling your software immediately.
Performance Validator uses your software’s debug information to perform the instrumentation of your software. Supported debug formats are PDB, TDS, DWARF, STABS and COFF. We can also use MAP files if line number information is present.
You don’t need to modify your software unless you are writing a service or working with IIS.
If you’re working with a service or IIS, there is a simple API you can use that you can “fit and forget”. It’s so easy to use you can leave the API linked into your release product – it will do nothing unless Performance Validator is present.
This simple 4-step process is how you profile your software.
Intuitive data displays show you the performance statistics as your application executes. You do not need to wait until your application has finished to view statistics for any function, file or DLL. The displays can be filtered to show you only the information that you want to work with.
Detailed, colour coded source code shows at-a-glance which functions and lines have executed and how long each took.
Performance Validator can be configured to collect all data or just the data you need. Powerful filters for collecting data and for displaying collected data give you maximum flexibility and control over how much CPU time is spent and how much memory is used collecting data allowing you to choose how much effort is put into a given task.
Performance Validator provides an API for using Performance Validator with services for the case when Performance Validator cannot inject into a service because of Windows NT security privileges preventing the injection (typically for services running at Administrator or system level).
The default options of Performance Validator provide profiling data for all DLLs and files in your application that have debugging information. If you wish to only create profiling reports for selected DLLs, or exclude certain file types or even specific classes and methods, Performance Validator has filtering capabilities to allow such customisation.
Performance Validator provides powerful HTML and XML reporting capabilities, allowing you to produce profiling reports that you can share with your colleagues or post on your company intranet. The HTML reports can include animated collapsible call trees and call graphs.
Performance Validator works with compilers from:

We support many versions of Visual Studio: Visual Studio 2022, 2019, 2017, 2015, 2013, 2012, 2010, 2008, 2005, 2003, 2002 and Visual Studio 6 are supported.
All 64 bit (x64) Windows operating systems are supported.
All 32 bit Windows operating systems from Windows 11 to Windows XP are supported.
If you’re using .Net and/or .Net Core, Performance Validator supports these technologies.
If you’re also using native code with your .Net applications, we’ve also got that covered, mixed mode applications are supported.
Performance Validator works with applications, services and IIS/Web Development Server, both native and mixed-mode .Net.
As well as the traditional performance profiling role that Performance Validator performs, Performance Validator can be used for interactive profiling and for creating profiling reports automatically as part of a regression test suite and/or overnight build.
Performance Validator also allows you to automate this process by launching Performance Validator from the command line. A full range of command line options allow you to perform unattended runs of Performance Validator, complete with HTML export and XML export, to facilitate regression testing as part of your overnight builds.

Example 1 Launch a program, record profiling data and save the session.
performanceValidator.exe -program "c:\myProgram.exe" -saveSession "c:\myResults\session1.pvm" -displayUI -refreshStatistics -refreshAnalysis -refreshCallTree
Example 2 Launch a program with a specific startup directory, record profiling data and save the session. A previous session is loaded and compared to the recorded session, the results are exported to HTML.
performanceValidator.exe -program "c:\myProgram.exe" -saveSession "c:\myResults\session1.pvm" -displayUI -refreshStatistics -refreshAnalysis -refreshCallTree -directory "c:\testarea" -sessionLoad "c:\myResults\session1.pvm" -compareByParentTime -exportAsHTML "c:\myResults\session2.html" -sessionCompareHTML "c:\myResults\comparison_1_2.html"
We update our software tools on a regular basis – on average about 26 updates per year. Updates are optional, you only need to download the most recent update to be up-to-date.
