I have a new TW installation with a 940GB encrypted root partition

When starting the machine, grub asks in text mode for the passphrase.
After entering the passphrase, it takes about 20s until the graphical boot
screen appears.

I feel this is much too long....

Has anyone a similar experience?

Perhaps around 10 seconds, running in a KVM virtual machine. Around 1
second on a real machine.

However, I am using "ext4". It is probably slower with "btrfs". I
don't have "btrfs" and encryption on the same machine, but "grub"
loading a menu from "btrfs" is noticeably slower than loading its menu
from "ext4".

Filesystem is irrelevant here. Encryption is done by LUKS, which is a
layer between raw block device and filesystem.
