A 4.7ish buildworld on my dual MP2000+ box with a aac controller took
about 17 minutes to build. Too bad current takes 30 minutes. gcc is
slower because it is trying to produce better code is the biggest
reason, although some of the overhead is due to the kernel I'm
running. -current takes about 28 minutes to build on the same 4.7+
kernel. I've blown away the stable part of this box, so recreating
these numbers may be hard.
