True, although I have read claims that under modern Linux kernels, it is
no longer the case that swap partitions give higher performance than
swap files. Regrettably I can't remember the details, but I assume that
since space for the swap files is pre-allocated, the kernel now keeps
track of where the sectors are on the device so that it doesn't have to
invoke the file system when writing to the swap space.

The other advantages mentioned are uncontroversially correct, though, as
far as I know.
