多年来，性能一直是UNIX™操作系统中许多变化的动力。本文给出了随着时间的推移所采取的系统性能的测量结果，并将测量到的改进与引起它们的算法变化联系起来。最显着的改进发生在执行表搜索，磁盘输入/输出和终端处理的方法上;这些都是由最近32位硬件中的地址空间和内存限制的释放所推动的。总的来说，32位机器上的变化使系统支持分时用户的能力提高了25%以上。
Performance has motivated much of the change in the UNIX™ operating system over the years. This paper gives the results of measurements of system performance taken over time and links the measured improvements to the algorithmic changes that gave rise to them. The most notable improvements have occurred in methods for performing table searches, disk input/output, and terminal handling; these have been driven heavily by the release from address space and memory restrictions in recent 32-bit hardware. Overall, the changes on 32-bit machines have yielded a more than 25-percent improvement in the system's ability to support time-sharing users.
