Obviously, benchmarking programs will often be much more complex than that example. They should be designed to emulate your environment as closely as possible.
Profiling is the gathering of performance information about an application. There are several ways to profile an application. Two that are part of the .NET Framework are:

or by opening a Command Prompt and entering
perfmon. When the System Monitor opens, click on
the Add icon on the toolbar to select and add any number of
