Encryption: Long delay after entering the passphrase

[H-Cl]

So far I only encrypted certain folders with gocryptfs (formerly with encfs).
Now I tried an installation with full encryption in VM-Ware and I have the problem, that it takes about 20s between entering the passphrase and the start of the grub menue.

The "Schwuppdizität" of the System itself is OK.

Is absolut normal for FDE with LUKS1.
There is nothing we can do.

Thanks for the quick answer. So I think that I will switch back to encrypting only critical data.
