Minimem is a free program designed to reduce the memory footprint of individual applications selected by the user. It runs in the background and will handle as many processes as requested.
If you’ve ever encountered a program that simply uses too much memory, Minimem will almost certainly be able to reduce it’s memory expenditure for you; just point Minimem to said app and watch its memory footprint magically decrease to a fraction of it’s original usage. It really is that simple.
