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.

Thanks,
