Memory bandwidths is commonly reported in MB/s not bits/sec and
also application throughput tends to be reported in B/s as well.
In general it seemed more natural to map application performance
to B/s. A toggle would be easy enough to report in both or just
bits. On the other hand iperf/netperf seem to report bits per sec.
