Profiling Performance with Rational Quantify

Rational Quantify is a runtime analysis tool that offers software developers and testers a practical solution for identifying bottlenecks, and then reducing or eliminating them through systematic performance engineering. Begin profiling performance just as soon as you have a working program, when it's easiest and most economical to make structural changes. Then continue tuning performance until you're ready to ship.

Note that Quantify's results include virtually no overhead from the profiling process itself. The numbers you see are the time your program would take without Quantify.

Quantify measures performance for:

§          Managed code in any source language that has been compiled for Microsoft's .NET platform, including C#, Visual Basic.NET, and managed C/C++, in assemblies, .exes, .dlls, OLE/ActiveX controls, and COM objects

§          Visual C/C++ code in .exes, .dlls, OLE/ActiveX controls, and COM objects

§          Visual Basic p-code, and native-compiled code in .exes, .dlls, OLE/ActiveX controls, and COM objects

§          Components launched by container programs

§          Microsoft Excel and Microsoft Word plug-ins
