PerformanceCounterInstaller Class
Assembly: System.Configuration.Install (in system.configuration.install.dll)
The following information might help provide a performance improvement when installing performance counters at application startup. Performance counter categories installed with .NET Framework version 2.0 use separate shared memories, with each performance counter category having its own memory. You can specify the size of separate shared memory by creating a DWORD registry key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\<category name>\Performance\FileMappingSize with a value such as 131072, the current default. If the registry key is not present, the fileMappingSize attribute value for the performanceCounters element specified in the machine.config file is used, causing additional overhead for configuration file processing. You can realize a performance improvement for application startup by the use of the registry key.
