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.)
