As far as I noticed, many networking functions a directly implement into the kernel.
So, if you will disable functions by config, it will not speed up things, it will cause only time lag.
Have tested to disable IPv6 support and it will increase boot time.
I will say, it’s not a good idea. Better let’s Debian/DietPi do this for you, if boot time is important.
If you will set it after boot-up, you have to wait for reinitialize the hole network stack.
Hmm, DietPi does it in the old Debian style with a single config file. I personally like this much more then using a network manager or the Rasbian way.
Sense of speed, DietPi approach is a good to go.
Have tested it. In some rare chases, with tweaked sd card settings, it will fuckup the hole overclock setting on some of my RPi devices.
In short, it only make sense to set SDRAM schmoo to get more than 500MHz SDRAM frequency (default is unset).
And bullshit is all over the internet. Many people creating content only by copy-and-paste without trying it seriously out or understand the background.
Here some good informations, but always keep a eye on it, you have a RPi Zero and not a RPi 3 or RPi 2:
It’s the picky sd card I ever own. With some devices this card will not boot up (timing problem on Odroid C1 and C2). And the speed is only at the very most ordinary.
I don’t use Samsung EVO+ in my SBC any more now. For mobile phone, as storage device, it will be okay. So all my get in there.
It correct. It the wrong parameter and the wrong overlay for newer kernel.

And please have a look at the output of:
root@RPi-Zero_W:~# dmesg | grep mmc
....

so you can see, if it work correct with your sd card.

Yes correct. On RPi2 and RPi3 (multi-core) it will be work much better.
And if you have a huge swapfile like in default config, you will get a significant drop on boot time.
But the main goal is overall system performance and response.
BTW: - have you notice the typo in dietpi-config dialog and dietpi.txt?
# >> Misc Options -----------------------------------

Don’t think to make a github issue for this.
