On my main machine 'make -j12 buildworld' takes 43:38.42 minutes to
complete; -j4 takes 1:53 hours to complete. My stripped down kernel is
built in 1:52 minutes... It's a AMD FX 6100, 8GB RAM, ZFS all around.
I'm shure I can improve those numbers, as I was running other stuff in
the background.

Some days ago, I dug out an older machine of mine (sporting a
PIII at 500MHz, 256MB memory). That machine needs ~25 hours to build world.
Crazy fast :D

To be honest, I don't exactly care a lot how long it takes to build a
new world/kernel. I'm happy as long as it finishes in a reasonable
timeframe (those 25 hours are stretching it a bit, though...).
