Bertha: A benchmark tool for high-performance storage subsystems.
John Lenehan, Dave Wagoner, Lewis Myers · Int. CMG Conference · 2006
The popular circa 1990 UNIX file system benchmark tool “Bonnie” has been substantially modified to form a distinct benchmark tool called “Bertha”. The features of Bertha that distinguish it from Bonnie, as well as most other benchmark tools, are 1) it generates substantially more I/O to challenge contemporary storage subsystems so that their capabilities can be better measured, 2) it offers a unique facility to “replay” I/O “transactions” that have been captured from actual production applications or simulations to more accurately suggest performance that will be experienced when using particular applications, and 3) extensive metrics reporting that provides more insight than what a single average value can provide.
