This section describes the procedures and options for collecting detailed performance data for an ASP.NET Web application by using the VSPerfCmd command line tool and the instrumentation method.
Note
The VSPerfCmd tool provides you with complete access to Profiling Tools functionality, including pausing and resuming profiling, and collecting additional data from processor and Windows performance counters. You can also use the VSPerfASPNETCmd command-line tool when you do not need this functionality. In comparison to the VSPerfCmd command-line tool, no environment variables have to be set, and rebooting the computer is not required. For more information, see Rapid web site profiling with VSPerfASPNETCmd.
