Doing a large 'make' does it for me - small difference, but measurable. I get the best poerformance by compiling out SMP alltogether though. As my machine spends most of its time doing 'make' then for me it's worth removing it entirely (aside from the fact that my machine isnt stable under HTT) -pcf.
