IOStone: a synthetic file system benchmark
Arvin Park, Jeffrey C. Becker, Richard J. Lipton · ACM SIGARCH Computer Architecture News · 1990
This paper presents a portable benchmark called IOStone that measures file system performance on a string of file system requests that is representative of measured system loads. Instead of isolating a particular aspect of file system performance such as disk access speed, or channel bandwidth, IOStone measures performance of the entire file system which includes components of disk performance, CPU performance on file system tasks, and disk cache performance, IOStone provides a basis for comparing performance of different file system implementations. It can also guide system builders in matching processor performance with file system performance. Measurements made using the IOStone benchmark indicate that a good balance between processor performance and file system performance is rarely achieved. Version II of the C language version of IOStone is available through electronic mail from [email protected].
