The goal behind DisableAllSwap is to ensure that no memory is ever paged
out to disk. If you have encrypted swap space, it's probably not an
issue if your have information swapped out to disk.

There may be some speed improvements from never having memory paged out
to disk but it's probably minimal.

If you'd like to test it, we'd sure would love to know if it works
properly on FreeBSD.
