I'm not sure whether a sarcastic overtone was intended, but I like it anyway. :-)

This (home) machine is switched off when it's not in use, so the startup time is more conspicuous to me. It's not my primary motive for using DMA, but if I can exploit it that way I'll be doubly pleased.

5 seconds.
hwtools runs after 46 seconds.

How would I measure that?
