摘要
进程切换的速度是衡量操作系统性能的一个重要指标。本文从硬件对进程切换的支持着手,描述了Linux内核在进程切换机制中对硬件的取舍及软件的设计思想,从而给出如何提高操作系统性能的思路。
The speed of process switch is one of the main merits which decide the performance of an operating system.This paper discusses the hardware support of process switch,and describes how to make a choice from the hardware support,and gives a design idea of software in the implementation of Linux kernel,and finally indicates guidelines of improving operating system performances.
