has anyone else experience a huge lag in how quickly your m1 starts up? It use to be super quick for me before. I would just open the laptop and boom, but now its sooooooo slow starting up. Any ideas what cod be causing this?
 
Are you confusing booting with waking from sleep? Waking from sleep is instantaneous. Booting is not.
Thanks. I think I know the difference. My point is my startup was very quick before but now is not. Very strange how this happened. Wish i had a video of how quick it wss before.
 
For you, I just shutdown my M1 MacBook Pro. From cold start to the login screen took 45 seconds. From login to my desktop took 14 seconds. From sleep, wake is instant.
 
About 16sec cold boot to logon screen...suspect it maybe a little faster as the monitor takes a little while to sync and display the login prompt. filevault is disabled - 11.3 Beta 2

I experience this after enabling FileVault. Before that it barely took 10 seconds.
 
Its taking 25 seconds for mine to boot up. I even see the loading bar never saw it before. Boot up would be in a matter of somethi around what APPLGeek mentions where it was 10 seconds or less. Not anymore and I havent made any configuration changes......stumped.
 
FileVault is usually a cause for longer boot times as a lot of data will be decrypted. But it is usually on by default or deliberate turned off.

When I open my system that is seeing it is instantaneously ready to go. However, if I power off the system it has always taken a while to start back up. It is not clear from your post when you are seeing the delay. However, here are my test results for a Power off and then power on. They are reproducible. The system is a MB Air M1, 8GB memory, 256 GB drive

Scenario 1: Shutdown system with 3 app windows open (Edge, Outlook, Spotify)

Time from Powerup after shutdown to login prompt:45 seconds
- During this time loading bar appears

Time from Login prompt to logged in and running, with previous 3 application windows open: 15 seconds
- During this time loading bar appears.


Scenario 2: Shutdown system with No applications running

Time from Powerup after shutdown to login prompt:42 seconds
- During this time loading bar appears

Time from Login prompt to logged in and running, with no previous application running: 9 seconds.
- During this time loading bar appears

It appears time to a usable system is a function of how many windows were open when the system powered off.

Encryption/decryption is done in hardware on the fly and its affect on performance should be insignificant. That's one of the benefits of the T2/M1 chips.

Cold boot has always been slow for me versus waking from sleep. Sounds like your device is shutting during sleep so you have to go through the long cold boot. Had this issue on 11.0.1 that have so far cleared up after erasing MacOS and doing a clean install from recovery.

something definitely wrong with big sur at the moment, or is it my M1 MacBook Pro? Twice on boot up i'd get to the log in screen and my trackpad wouldn't register movement, the mouse cursor wouldn't even move, hard shut down and powered back on fixed the issue twice.

yesterday I noticed boot up was slower by about 5 seconds, went from boot up to a black login screen, had to power off the machine, turned it back on, black screen hasn't happened again and boot up time seems like it backs to normal speeds. strange one. 🤔
