So we're getting into a situation where 2.6 will have either server or desktop
tuning? I guess if one can't fit all (ideal) then this is a good compromise.
What I don't understand is why the anticipatory scheduler takes longer to
compile a kernel without any load running? This happened with previous tests
of the as scheduler too.
