i tried to rum systemd-analayze:

Startup finished in 21.600s (firmware) + 5.450s (loader) + 8.839s (kernel) + 2min 50.287s (userspace) = 3min 26.177s 
graphical.target reached after 2min 50.240s in userspace

and for systemd-analyze critical-chain:

The time when unit became active or started is printed after the "@" character.
The time the unit took to start is printed after the "+" character.

                                └─-.slice @5.873s

it was telling me before that docker and snapd are slowing me so i deleted them, i reduced the userspace from 4min to 2min 50s
and this is the new result.
what can i do more?

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
