Right, and the answer was:  One box has a much faster CPU,
so it's user time is smaller, but buildworld isn't purely
CPU-bound, and because of I/O delays the real times end
up to be about the same.  In other words:  The faster box
had to wait more often for the disk than the slower box.

If both of your machines have enough RAM, it would be
interesting to repeat the test with /usr/src being in a
RAM disk, so read I/O doesn't play that much of a role.

Best regards
