DMIPS is a Dhrystone-MIPS benchmark, which has some restrictions as to what can be enabled andtested. More information can actually be found on the ikipedia entry on Dhrystone: http://en.wikipedia.org/wiki/Dhrystone
In a nutshell, the Dhrystone does not benchmark anything that uses Floating Point, it only measures program iteration *completions* per second, rather than instructions, and so on. It is generally used as a standard to compare different processors/architectures, and does nottake peripherals into account (in order to keep the "standard' a standard)
In the "Microcontroller" configuration, we enable a larger test system (peripherals, etc) set for comparison, which is why the usage is higher. This is the configuration you should expect to see the numbers listed under normal use-cases
