PenguinOMeter: A New File-I/O Benchmark for Linux

PenguinoMeter is a new open-source benchmark for Linux that measures file-system data transfer rates. PenguinoMeter allows the user to specify the file-system workload to be used in the benchmark in a very flexible manner. The workload specification is patterned after that of the Intel® Iometer benchmark; the current version of PenguinoMeter can read configuration files produced by Iometer. A series of comparisons between Iometer and PenguinoMeter is used to demonstrate that the workloads generated by these two programs appear to be identical. As an example use of PenguinoMeter, we compare the file system performance of Microsoft® Windows® 2000 Professional and Linux 2.4.9.
