AIUI (and please correct me if I'm wrong) using tmpfs for /tmp makes a
fake filesystem (like what we used to call a RAM-drive) in memory (using
both RAM and swap).

Is the advantage purely one of speed, because most of the time (you
hope) you're manipulating the virtual /tmp/* files in RAM rather than
reading and writing to disk?

And when swap is being used for this too, it's no slower than /tmp/* on
disk would be anyway?

To do this, how much extra swap needs to be allowed?
