Slow boot time with Bullseye....

[ramblin]

I recently did a fresh install of Bullseye and notice my boot time is much slower than Stretch. Looking further it seems my Network Manager is to blame ?? After researching NetworkManager I find many say disable it while others say it won`t speed up boot time a bit. Do I understand correctly that it does not hold up booting in any way but waits till everything is configured before connecting? Connection is and always has been hardwired thru a WDS Station. 30 sec. is not an issue for me and I happy to just leave things as is unless there is an underlying prob. with a driver not loading or wrong or ancient hardware, then i want to fix it. I installed the package: firmware-realtek (20210315-3). Any advice on how to proceed from here?

Hello,
You probably will get hints reading a previous thread: see viewtopic.php?p=757565#p757565

This is what I have:

In summary, disable what you don't need.
Easy one plymouth... Do you really need this ??

Yes.

I find systemd-analyze to be pretty useless because it doesn't indicate the actual time taken to reach a graphical desktop at all. The plot option can give a better picture (unsurprisingly) but even that's not very good for much. Also try the critical-chain option, which is more appropriate than blame IMO. The man page explains the limitations of the options.
