Fedora 38 Workstation boot time and memory improvements

[Gordon Messmer]

I didn't mention this in time to even discuss whether it'd make a good 
addition to the release notes, but I think users will be happy to see 
that Fedora 38 Workstation boots faster and uses less baseline memory 
(measured from a session logged in to GNOME with only a terminal 
application running to get the output of the "free" command).


Fedora 37 Workstation:

     $ systemd-analyze
     Startup finished in 1.141s (kernel) + 4.082s (initrd) + 11.632s 
(userspace) = 16.856s
     graphical.target reached after 11.602s in userspace.

     $ free
                    total        used        free      shared 
buff/cache   available
     Mem:         8117668     1534288     4896332       36748 
1687048     6291452
     Swap:        8117244           0     8117244

Fedora 38 Workstation:

     $ systemd-analyze
     Startup finished in 1.149s (kernel) + 4.593s (initrd) + 8.821s 
(userspace) = 14.564s
     graphical.target reached after 8.463s in userspace.

     $ free
                    total        used        free      shared 
buff/cache   available
     Mem:         8117664     1092748     5816496       40588

Interesting. Can you pin down from you analysis where the difference comes from,
especially in user-space? I'm asking for a friend :-)
... the point being: Do upgrades profit as well, or should we review systemd services at
boot which might remain from F37 after upgrade for new defaults?

Just a note: GDM gets shut down after a timeout. So the stats might differ
whether you collect them directly after login or a short while afterwards.
Something to be aware of.

If there are really some memory improvements in GNOME 44, it will affect
upgrades as well, of course. At this moment I'm a bit skeptical about the
presented numbers, though.

The boot time improvements came from removing iscsi from the critical 
path.  There's no longer a dependency on network-online in the path to 
graphical.target.

The memory improvements came from allowing packagekitd to shut down on idle.

Thanks, and I can confirm that on upgrade F37->F38, iscsi does get removed from cp.
Great!
