Running Slackware-current, using kernel 6.18.13. With a SSD, I'm seeing regular boot times of 12-15 secs, from GRUB2 to SDDM login screen. After supplying credentials, add perhaps 3 seconds more to a fully functional KDE Plasma 6.6 desktop.
It should be noted that Slackware is a systemd-free distribution which uses a simple BSD-like init system. I point out this because early on in systemd's development, one of the selling points was that "it would enable you to have faster boot times".
