When I first got this machine in December, it booted insanely fast, IIRC less than 10 seconds to login prompt. With the latest Big Sur 11.4, startup time has more than doubled- from startup chime to login window is around 28 seconds. It seems the boot progress bar gets to about 25% and hangs for quite awhile.
I'm not using any weird apps or utilities, all typical light usage apps. No external devices. Has anyone else seen this?

Try a SafeBoot https://support.apple.com/en-us/HT201262
Takes noticeable longer to get to the login screen, does a disk repair before it fully boots up, and certain system caches get cleared and rebuilt, including dynamic loader cache, etc.
Reboot as normal. Caches get rebuilt automatically.

Tried, doesn't work on M1. I've viewed system.log but it doesn't really shine any information on what the hang up is. I've got a strong Linux background, but am scratching my head trying to find useful information.

Verbose Mode
Back when I was studying for Mac OS X certification, verbose mode was a popular way to see the details of the Mac startup process. Basically what it does is show all of the processes that are being loaded in the UNIX underpinnings of macOS. When there’s something that is keeping a Mac from booting normally, or if the boot is taking longer than usual, verbose mode can pinpoint the process that is at fault.
Enter verbose mode on an Intel Mac, and all of the processes scroll by. Now, there is a way to enter verbose mode on an M1 Mac using a change in NVRAM (non-volatile RAM), but that’s not something that should be done without really knowing what you’re up to as any issues may lead to a complete system reinstall.
To set up your M1 Mac to go into verbose mode, open a Terminal window (either from a normal boot or from the Utilities menu in Recovery mode) and type in:
sudo nvram boot-args=”-v”
Once the command has been entered, quit out of Terminal and reboot the Mac to enter verbose mode.
As a safer alternative, reboot the M1 Mac in Recovery mode (see instructions earlier in this post). When the Recovery mode screen appears, select Recovery Log from the Window menu. This log records the boot process, and can be set to show all logs, errors only, or errors and progress.
Unless you are aware of what all of the various startup processes entail, verbose mode is really not a tool for general usage.
Guess so. Must be code bloat with Big Sur. My old 2013 MBA boots significantly faster with Catalina. I wish developers would take some time and clean up and optimize code. With this insane hardware we have now, everything should open in the blink of an eye. Seems like we're taking a step forward and two steps backwards.
Thanks, but the nvram command doesn't work. I found an article that claims it stopped working after 11.2.
I went into recovery and checked the recovery log. It's only 1 second of logging and it went quickly into recovery.
I have tried the Safe Boot, and run the disk repair, no issues were found. Is there a verbose boot option on Big Sur? I can't seem to find one.
Command + v immediately at startup on Intel. Not tried on M1.
My mba takes about 25-30secs so seems like your Mac is ave.
The NVRM (PRAM) reset not applicable with M1 Mac like on the Intel version.
