Well, in principle it should be faster to build in swap than on a
regular fs as tmpfs will only write to the backing swap when it runs
out of space, whereas regular filesystems will write out more
frequently (and also try to make guarantees about consistency in case
of unclean shutdowns, which tmpfs+swap doesn't need to care about).
