Are you looking at the memory reported by top or so on and using that to
conclude jack is taking a lot of ram?

Jack uses (lots of) shared ram to communicate, so the consumption looks
really scary, whereas infact most of the memory is only allocated once.

As long as you have 256MB physical ram or more you will be fine.
