注解

以下信息可能有助于在应用程序启动时安装性能计数器时提供性能改进。 随 .NET Framework 版本 2.0 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有自己的内存。 可以通过在注册表项中创建名为 FileMappingSize 的 DWORD 来指定单独的共享内存的大小，HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\<类别名称>\Performance。 FileMappingSize 值设置为类别的共享内存大小。 默认大小为十进制131072。 如果 FileMappingSize 值不存在，则 fileMappingSize 使用 Machine.config 文件中指定的元素的属性值 performanceCounters ，从而导致配置文件处理产生额外的开销。 通过在注册表中设置文件映射大小，可以实现应用程序启动的性能改进。
