Slow boot and shutdown

Maybe you could try the suggestions 1. and 2. from the following post:

  1. You may want to check to see if there is some kind of option for “fast boot” in your BIOS. If not, you could try to see if you can disable as much as possible in the UEFI firmware menu (bios). When the machine POSTs, it polls for anything and everything that may be attached to the machine. For things like USB, that can be pretty slow. So if you can disable them, it should speed things up. Once the kernel is loaded, it will re-poll for devices anyway and get everything going.

  2. You could combine the above with changing the default/fallback boot path. Some UEFI firmwares require a bootable file at a known location before they will show UEFI NVRAM boot entries. The solution is reinstalling or moving the GRUB EFI executable.

This should shave off some of that boot and shutdown time.

Note: Just ignore the encryption related stuff in that thread.
