Because not everyone with a Samsung 970 Evo or Evo Plus is experiencing (or reporting) slow boot times with Monterey, the jury is still out on the exact cause. But
@manfriday saw this in his boot log:
Code:
kernel: (apfs) spaceman_scan_free_blocks:3153: disk5 scan took 0.921803 s, trim took 93.611921 s
Notice that trim took over 93 seconds. But setting
SetApfsTrimTimeout to 999 (i.e. disable trim) did not make a difference.
Some of the drives I use (without any slow boot issue) are:
- Silicon Power
- ADATA SX series
- Sabrent Rocket
- Crucial P1/P2
