So much so that, clocktick for clocktick, it is probably STILL several times faster than the now-ubiquitous x86 architecture. Shame they haven't caught up :-( (I'm thinking particularly here of a ring-jump, but I think it was just blindingly fast regardless - linux goes to great efforts to avoid such jumps, Pr1mos didn't care...)
