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

Grumble. So this became the default in F33, and I jumped from F32 to
F35, so I missed the excitement. Only now to find out the change.
If I had 'known' this, I would have looked at my memory/performance
issue differently. I WAS showing 5Gb memory used and ~5GB swap used
back when I started this thread on the 11th:
$ free
total used free shared buff/cache
available
Mem: 7380668 5146100 1776840 1364 457728 1948864
Swap: 24157176 5270956 18886220
At that time, I had significant system delays when doing various tasks.
Looking back, I will attribute this to zram operations.
Immediately:
sudo systemctl stop swap-create@zram0
Permanently:
sudo touch /etc/systemd/zram-generator.conf or sudo dnf remove
zram-generator-defaults
As of now, I am seeing zero swap used and zramctl being small:
# zramctl
NAME ALGORITHM DISKSIZE DATA COMPR TOTAL STREAMS MOUNTPOINT
/dev/zram0 lzo-rle 8G 4K 80B 12K 4 [SWAP]
So I will wait a few days and see how growing Firefox impacts all of
this with the additional 8GB real memory...
thanks
