Generally speaking, swap is only significant when the system
runs out of RAM and needs to swap. It doesn't make anything
faster or slower. Swap is disk I/O, which is slower than
memory I/O, so when swap is being used, the system is slower,
but still responsive - the opposite of being non-responsive
and maybe crashing / blocking due to running out of memory.
You _can_ understand the presence and use of swap as an
increase of performance, compared to that alternative. :-)
