The end result is that disabling swap I get less free memory, as I said,
although not as much as I thought:-)

Which raises some interesting questions: if you have ANY free memory,
why is swap being used at all?

Because hibernation forces everything into swap. If some chunks are not
needed when the computer is thawed, they stay out of the way in swap,
leaving more memory free.

In the limiting case, that you have over a Gig of free memory, then with
your present process set you don't seem to need swap at all. The
'swapoff' worked. You could have left it off. Were any error logged
during the time it was off?

If I leave it off the computer is slower. Don't you see?

And I use hibernation, I need it.

Are you using a tmpfs by any chance?

Well, yes, of course, those that systemd requires:

Telcontar:~ # df -h | grep tmpfs

Filesystem Size Used Avail Use%

devtmpfs 3.9G 100K 3.9G 1%
tmpfs 4.0G 1.1M 4.0G 1%
tmpfs 4.0G 407M 3.6G 11%

/run, /var/lock and /var/run are the same one.
