General Unix Linux and other Unix-like operating systems use the term "swap" to describe both the act of moving memory pages between RAM and disk. It is common to use a whole partition of a hard disk for swapping. However, with the 2.6 Linux kernel, swap files are just as fast as swap partitions. Now, many admins (both Windows and Linux/UNIX) follow an old rule of thumb that your swap partition should be twice the size of your main system RAM. Let us say I’ve 32GB RAM, should I set swap space to 64 GB? Is 64 GB of swap space really required? How big should your Linux / UNIX swap space be?

Why not?

If you are running a system with 32 gigs of memory you intend to do SOMETHING memory intensive with it. Why not use 64 gigs for swap? Again, it seems like you intend to do something with it, and how expensive are disk drives these days? With the cash you are dumping into memory you can spend something on some beefy disk drives.

Besides, this isn't a major life decision here. Choose something. The installer's default will be fine. If you need more make a swap file.
