I would just like to add some numbers:

system: freebsd 6.0 i386
job: make buildworld buildkernel

When kernel and world are compiled with -g and
witness,memguard,invariants are switched on the job takes 120min.
With witness,memguard,invariants turned off it takes 66min.
1/3 More speedup when using world and kernel, compiled with -O2 instead
of -g, and yet 10% more speedup when removing J option from
