Hi Peter,


The bandwidth in dm-band is determined by the proportion of the
processing time of each device's tokens(I/Os) to the processing time
of all device's tokens(I/Os).
The processing time of one token(I/O) is determined by one I/O cycle 
include seek latency, interrupt latency, etc...

Thanks,
Ryo Tsuruta <ryov@valinux.co.jp>
