I'm reasonably certain that on modern kernels the performance
overhead of swap files is negligible (back around ~2.2 this was not
the case). In fact it wouldn't surprise me if the overhead due to
seeking to a dedicated partition (regardless of its location) were
far greater. Of course, this wouldn't apply if the swap were on a
dedicated (or mostly dedicated) drive.
But in any case all of these swap performance issues should not
matter swap activity (and the impact of swap performance) on a
properly configured system these days should be very low per previous
comments. It now generally makes sense to optimize swap
configuration for reliability and administrator convenience rather
