Hmm... Yes, maby, but I did, as was adviced in the article (http://aumha.org/a/parts.htm):
Put the swap file partition as the first partition on the second drive. If you do not have two separate hard drives, the performance gains from this placement will be offset by certain performance degradations, and only by experimentation on your unique computer with your unique usage pattern can you determine whether the net change is a gain, a loss, or no difference at all.
In either case, there are other significant advantages to having the swap file on its own partition, so you may want to do this even if you get no performance gain, or even if you get a small performance loss. Some of these issues are discussed more completely elsewhere in this article, but, to mention them briefly, they include containment of “fragmentation contagion” to the rest of the drive (which can have quite a significant positive effect on overall machine performance);
