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. http://wiki.freebsd.org/JeremyChadwick/Bizarre_CURRENT_experience I have no idea if your problem is the same as mine. This is purely speculative on my part.
