Yes, there are application that don't utilize the interconnect and
will show the same results on 1GigE and 100GigE. I was referring to the
application that do utilize the interconnect, and those are the ones
that I test.
Anyway, the I/O is not just bandwidth, but also provides latency, CPU
and other important characteristics, and all of them need to be
