FreeBSD lets you have either or both, but a swap partition is faster.
If you use a swap partition, block N is at disk location B+N where B
is the base of the partition. If you use a swapfile, you have inodes
and indirect blocks and such, so random access to a large swapfile
might have to read one or two overhead blocks for every swap block.
