Performance-wise? There's no difference
(http://serverfault.com/questions/25653/swap-partition-vs-file-for-performance#25708).
Flexibility-wise? Well, if you put your swap partition on LVM, then you
can move it around and extend it just as easily as you could a file.

Perhaps the only advantage a partition has is that you can fairly easily
ensure it's at the fast end of your disk (that said, balance up how long
the head's going to be there, with how long it takes to get there).

 
 One thing to know about up front - my new Debian setup is on my home
 server.  It runs 24/7 and I *never* suspend/hibernate it.  So since it
 never has to resume from a swap partition, that particular item is moot. :-)
 
 So, what is the common best practice (more-or-less) consensus on the
 subject these days?

A partition is probably the most common.

Pretty sure the partition is far more common. The file version is
there if you need it, but hopefully you don't. Having the pages sit in
a file on top of a filesystem just adds some extra layers, probably
decreases performance a bit, AFAIK

Are you sure you need swap at all? If so, will your server still
deliver acceptable performance if it is actively swapping? If yes,
then the performance of the swap space clearly matters. If not, you
want to avoid that anyways and just keep the swap around in case that
something badâ„¢ happens (to avoid the OOM to kick in immediately).

A swap file gives you more flexibility at the cost of a slight
performance loss. As swap is nowadays not really needed, I would
hence suggest going with a swap file.

Best regards,

Claudius

I use swap partitions on all my computers, but on a live USB stick I use
a swap file.  The reason for using the file is so I can easily change
the size of the swap space (for instance, if I run out of room for my
data).
