[gentoo-user] Memory manager

Do systems run different memory management when swap is on versus no swap?  I know that in the past it was recommended to have at least a small swap so the system used a better memory manager.  Wondering specifically if I should set up a small ram drive for swap just to get better memory management or if I should run swapless as this particular machine has a slightly obscene amount of ram available so I shouldn't need a proper swap partition unless it affects memory management.
