I think you have a misunderstanding as to what swap is for - it's not
for memory-hungry applications. Swap is not a replacement for memory.
It's good in cases where you have a lot of applications and many of them
are idle and you can afford the swapin/swapout. Swap is a very bad
substitute for memory-hungry applications. You need to buy more memory.
