This is what I meant about being dogmatic up thread.  You're being a
anti-swap zealot here.

Yes, using swap is slow. It's slow because using the disk is slow.

If you are using the disk because tmpfs is being written out, or
because your tmpfs is just a file system is the same thing.

Tmpfs just has the advantage of minimizing the disk activity— both in
cases where none is needed, and in cases where it is.

Really, you should try it.  It works very well and does not make your
machine perform poorly, even when under memory pressure.
