课后延时服务存在的问题及建议(学校课后延时服务存在的问题)

经常听人说用windows 7玩网游，网络延迟比较高，就是ping比平时xp高一点，一直找不到原因，很苦恼。今天，我们终于找到了原因。原来是Win7的一个服务在作怪。

This service is called Multimedia Curriculum Schedule.

这项服务的官方解释是：

The Multimedia Class Scheduler service (MMCSS) enables multimedia applications to ensure that their time-sensitive processing receives prioritized access to CPU resources. This service enables multimedia applications to utilize as much of the CPU as possible without denying CPU resources to lower-priority applications.

MMCSS uses information stored in the registry to identify supported tasks and determine the relative priority of threads performing these tasks. Each thread that is performing work related to a particular task calls the AvSetMmMaxThreadCharacteristics or AvSetMmThreadCharacteristics function to inform MMCSS that it is working on that task.

For an example of a program that uses MMCSS, see Exclusive-Mode Streams

就是这个服务让我的PING这么高。问题是我发现了，那怎么解决呢？很简单。关掉它。

禁用方法：开始-运行-注册表编辑，

展开[HKEY _ LOCAL _ MACHINE/SYSTEM/current control set/Services/Audiosrv]双击打开右侧的依赖服务项目，

删除MMCSS(其他不要删除)，最后保存退出。

设置要重启电脑后才能生效，然后关闭并禁用服务中的多媒体类调度器，再进入游戏看看有没有改进。
