Good point. At anything reasonable, I'm seeing VERY nice performance.

Try bumping NR_TASKS if you have lots of things configured as modules
(and use 2.1.131pre-3.. fixes vm tuning).. you should be pleasently
suprised. I can do make -j from hell and get very nice performance
until I run out of bandwidth. (easy to get rediculous.. I ran my box
to slightly over 300 loadav w. 1100+ tasks looking for fs corruption :)
