These two threads do not suggest there is any significant performance 
difference between swap file and swap partitions:


If that's meaningful for you, than by all means use a swap file.  But going
through the filesystem is never the fastest way to disk.  If that were the
case, then Oracle would never offer the ability to use a disk in raw mode
for speed.  You don't have to configure this way, but it is offered for
speed.  But then again, a home user never taxes a system like a business
system.  If you are more comfortable using a swap file, then use it.
