Fresh installed untuntu 23.04 very very slow to start

[kalpana]

is there a way to reduce the seconds of the following services to speed up the start up ??

systemd-analyze blame
29.518s plymouth-quit-wait.service
21.894s e2scrub_reap.service
16.746s NetworkManager-wait-online.service
12.412s snapd.service
