With it compiled in, your first DOS mount doesn't take as long.
8-).
Without it compiled in, your kernel is smaller, so you have more
room for programs, as long as you don't mount an MSDOS FS. If you
run enough programs to use up all your real memory, you have more
real memory, so you will typically swap less and the machine will
act faster.
