When building world/kernel, do you see odd behaviour (on CURRENT) such
as the load average being absurdly high, or processes (anything; sh,
make, mutt, etc.) getting stuck in bizarre states?  These things are
what caused my buildworld/buildkernel times to increase (compared to
RELENG_7).  I was using ULE entirely (on CURRENT and RELENG_7), but
did not try 4BSD.  I documented my experience.

I have no idea if your problem is the same as mine.  This is purely
speculative on my part.  (And readers of that Wiki article should
note that the problem was not hardware-related)
