The disk to disk aspect is distorting but he's using similar tests for each case. In many case disk to disk is the right way to test anyway, its what you actually do in the real world. ttcp can do similar testing without the disk layer being involved if that matters.
The closer a test gets to real world situations, the harder it gets to understand what happens. Many moons ago with a former version of the network drivers they turned to run disabled a larger portion of time, so we were unable to get interrupts in to the dasd driver. Any network benchmark receiving data would fill memory and slow down. It shows that running disabled is bad, but that was not the intention of the test...
