There are other commands allowing you to analyse (no relation to sddm-theme)
systemd-analyze blame
systemd-analyze critical-chain
see: man systemd
Last not least SDDM+1 will contain sddm-theme-maui as fallback - so you can test if it's "faster" with that.
A good hint is to disable Desktop-restauration, don't know why this is enabled by default (?). Always start with an empty desktop-session – speedy.
