I am using full disk encryption on Fedora 9 alpha and it has not caused much slowdown at all.  Since it encrypted the entire logical volume swap is included.

If hitting swap is an issue, you have other problems.  (You need to buy more RAM.)  It speed is really an issue here, then you need to look at a hardware upgrade.

Of course, this depends on what operating system you are using.  If you are using Windows, then I cannot help you.  (Except maybe in getting off that insecure monstrocity.)
