I understand what you mean, but I think that I will cut the time for loading device unit if I keep those from appearing on my plot.
I want to do a try to temporarily disappear some kinds of device units and then I'm supposed to measure boot speed depending a board of mine.(Actually, I believe that loading time for device unit affects to boot speed) What do think that loading time for device units doesn't affect to boot speed at machine?
