Windows XP中每个线程时间片需要多长时间? [英] How long does it take each thread timeslice in Windows XP?

问题描述

我试图找出Windows中每个线程时间片(量子)要花费多长时间，但是我发现的唯一信息是关于时钟滴答从15到20ms或20-30ms. 我如何找到此信息? 我认为它可能因操作系统而异，但我不确定. 感谢您对此问题的任何建议.

I am trying to find out how long does it take each thread timeslice (quantum) in Windows but the only information that I found out is about the clock ticks being from 15 to 20ms or 20-30ms. How can I find this information ? I think it may vary from OS to OS, but I am not certain. I appreciate any suggestion on this subject.

谢谢.

推荐答案

此知识库文章有关Windows 2000 Server版本的一些信息:

This KB article has some information on Windows 2000 Server editions:

当前在Windows中，三个量子等于10毫秒(单处理器)或15毫秒(多处理器Pentium).这取决于为您的计算机选择的硬件抽象层(HAL).原始设备制造商(OEM)HAL可能具有不同的值.选择后台服务时(如在典型的服务器安装中可能会选择的那样)，当前使用固定为36个量子点的时间片.

Currently in Windows, 3 quantums are equal to either 10 milliseconds (single processor) or 15 milliseconds (multiple-processor Pentium). This depends on the hardware abstraction layer (HAL) selected for your computer. Original Equipment Manufacturer (OEM) HALs may have a different value. Time slices that are fixed at 36 quantums are currently used when background services are selected (as you might choose in a typical server installation).

因此在多处理器奔腾上，一个量子将为5毫秒，而时间片将长达180毫秒.对我来说，那似乎很大……

So on a multi-processor Pentium, a quantum would be 5 ms and a time slice as long as 180 ms. That seems quite large to me, though...
