I've heard that the swap should be as close to the center of the disk
as possible- does that mean that I should use hda1 as swap? Opinions
welcome. Thanks.

I have 2Gb of RAM on my Dell 5150 (3.2 Ghz P4).

I have 1 Gb of swap set up and I as I type this post, 176 Kb (yes Kb) is in use. Given this, I am not sure that the location of the swap space is critical.

Even when running heavy analyses using R (http://www.r-project.org/), I rarely see much swap being used.

BTW, my swap is also encrypted (along with /home, /var and /tmp) using dm-crypt/LUKS and I don't see any notable performance hit using a 7200 RPM 60 Gb HD.

The old guideline of using 2x RAM for swap is, I don't believe, applicable with this much physical RAM installed and seems to me to be a waste of HD space.

HTH,
