I think the true test (benchmark) should be all on one disk, since most machines that are bought off the shelf only have one disk. > How about mounting of /usr/obj?

I think this needs to be the case since most newbies don't know about the async flag and mount defaults to !async in the absense of flags. So here's my vote for the benchmark standard: /usr/src and /usr/obj on one disk with !async CFLAGS=-O -pipe make cleandir && make world Or as Simon Shapiro pointed out, start with the lowest common denominator, throw in some options, and see how much things improve.
