I'm using our own tool, which issues I/Os in prallel in a specified period and counts up how many I/Os are issued and how many bytes are transferred in the period. I'm also using our own tool for measurement of throughput variation to see the internal data of dm-ioband. This tool is implemented as a kernel module.
