Good grief. I could be hallucinating, but it seems that
a make world finished in about 2.5 hours on this box. This
is 3/4th GB memory and 700+MHz. This was with 5.3 here.
Does it make any sense to use O3 when compiling stuff,
when stuff includes world/kernel/drivers? Does upping the
optimization make any significant difference in system
performance, in other words? Kent? Anybody?
