Login with encrypted /home takes roughly 1 min instead of 1 sec

Since roughly 1 week I face an annoying problem.

I have a LUKS encrypted /home partition which is automatically unlocked and mounted during login either via GDM or on tty. Since one week this login takes very long on both GDM and tty on the first try after boot.

What could this be?

Re: Login with encrypted /home takes roughly 1 min instead of 1 sec

why would you mount on login
you could close and reopen the luks patition to check if that the problem
if it have multiple key slot you could add a "--key-slot=$number" option becuse it will test from slot 0

#cryptsetup luksDump /dev/sd...

time cost sould be~ "Time cost:  4" because you are using a keyfile so no need to hash it
use option --iter-time 1 when adding key

$man cryptsetup luksAddKey
