I wondered why they needed root access, or even installing new
software, just to see if a disk was MBR or GPT. I just:
$ udevadm info /dev/sda | grep PART_TABLE_TYPE
E: ID_PART_TABLE_TYPE=gpt
$
(The alternative is E: ID_PART_TABLE_TYPE=dos.)

3/1 or 4/0.

When I used MBR disks, I found four partitions quite adequate for
two root filesystems (versions stable and either of stable±1),
swap and /home (eventually encrypted). With GPT, I include a 3MB
BIOS Boot, giving improved alignment whether needed or not, and
a 500MB ESP, which can be used as swap if not required.
BTW partition alignment is one thing I'd check for general slowness,
and it's obviously worth checking systemd-analyze blame on a
system that is sluggish to boot.
Back in March last year, you (OP) reported a very similar problem
(which happened to grow into a very large thread). Did you work out
what that problem was?

My i7 laptop only has 16GB memory, and I don't give it any swap
(I'm generous with overprovisioning). My two desktops (14GB and 8GB)
both have ½GB, which they never touch.

Yes, do. I wouldn't be able to keep track of what was where with a
scheme like that.
