The rotational speed of the disk will always be highest at the outside
edge. It has to be, just by the laws of physics.
Here's a link to the Partition How-To from the Linux Documentation
Section 4.4.3 covers placement of the swap partition.
Only older disks used the same number of sectors per track... I am not
even sure that many people have disks of that variety anymore. The newer
disks cram in as many sectors as they can, which means that you get
better performance at the edge rather than in the middle.
