Re: No Swap Allocation in FSTAB

[Barry Scott]

The SSDs are a lot slower than compressing a page into RAM.

There was extensive discussion on the Fedora Devel list when this change was proposed.

Personally I was convinced that this change is an improvement for any system that is under
memory pressure. I'm not going to try to recall the discussion as I may get some details
wrong.

I switched it on in F33 and have for over a year seen no down side for my work loads.
My work loads are file+email server, firewall, KDE desktops, Kodi music server.

At my work once we get on to Centos 8 I'm planning to performance test with zram swap.
We have a work load that is very sensitive to disk I/O spikes and there is some sad
code that uses swap for 10s to 15s every 20mins of so that I want to make go away.
We have RAID-10 SSD where we see issues.
