i/o generator

Back to search · Project homepage

Description

iogen is an i/o generator. It forks child processes that each run a mix of reads and writes. The idea is to generate heavily fragmented files to make the hardware suffer as much as possible. This tool has been used to test filesystems, drivers, firmware and hardware devices. It is by no means meant as a performance measuring tool since it tries to recreate the worst case scenario i/o.
