PerformanceCounterInstaller 类

指定 PerformanceCounter 组件的安装程序。

**命名空间:**System.Diagnostics
**程序集:**System.Configuration.Install（在 system.configuration.install.dll 中）

语法

声明
Public Class PerformanceCounterInstaller
    Inherits ComponentInstaller
用法
Dim instance As PerformanceCounterInstaller

public class PerformanceCounterInstaller : ComponentInstaller

public ref class PerformanceCounterInstaller : public ComponentInstaller

public class PerformanceCounterInstaller extends ComponentInstaller

public class PerformanceCounterInstaller extends ComponentInstaller

备注

下面的信息会有助于在应用程序启动时安装性能计数器时提高性能。随 .NET Framework 2.0 版一起安装的性能计数器类别使用单独的共享内存，每个性能计数器类别都拥有自己的内存。使用一个值（如当前默认值 131072）创建一个 DWORD 注册表项 HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\<category name>\Performance\FileMappingSize 可指定单独的共享内存的大小。如果该注册表项不存在，则使用 machine.config 文件中指定的 performanceCounters 元素的 fileMappingSize 属性值，这样会增加配置文件处理的开销。使用该注册表项可以实现应用程序启动时的性能改进。
