Um, I did not know I set up zram?  How did that happen.  Is zram now
part of the basic Fedora install?

It has been a while my using zram.  How do I disable it for now? With
16GB real memory and 16GB real swap partition, I want to see how things
are working...

thanks

Immediately:
sudo systemctl stop swap-create@zram0

Permanently:
sudo touch /etc/systemd/zram-generator.conf or sudo dnf remove
zram-generator-defaults

Asking the interesting question: Why would you want to ever do this?  RAM is ~10x faster than SSD and 100x faster than spinning disk.  Unless your system is so ancient and CPU-constrained that you are unable to afford the relatively low compression costs, making use of all available RAM at all times seems like a better move than stopping ZRAM swap.
