IOzone

What is IOzone?

The IOzone filesystem benchmark tool generates and measures a diverse range of file operations, enabling comprehensive analysis of a system's file I/O performance. The benchmark can assess read, write, re-read, re-write, read backwards, read strided, fread, fwrite, random read, pread, mmap, aioread, and aiowrite operations, providing a thorough evaluation of a vendor's computer platform. This versatile tool empowers users to deeply understand the file I/O capabilities of their system, informing performance optimization and decision-making
