I assume by "this", you mean using the SD as swap, and have not (yet)
bought extra RAM.

I vote for "optimistic perception", because I really can't see how it
can possibly make it run faster.  It's always going to be orders of
magnitude faster to use system memory than swap space.  When you use
swap, you by definition are trading more virtual memory space for
slower speed whenever memory needs to go back and forth to swap.

Are you sure you're even using the swap space?  When you run top, does
it say that any of it is in use?
