I have been distro-hopping for years and finally have settled on Manjaro for the last 6 months. My only problem is that full disk decryption takes slightly over a minute to decrypt my HDD.
I have seen various posts in the forums regarding slow decryption at boot.
I have run various distros with FDE and manjaro is the only one that has this issue in more than one system. I am not a computer major so I have no clue what the technical reason is for this. Maybe a GRUB issue.
The following thread could shed some light;
Please fix this as I want Manjaro to good enough to compete with opensuse/ubuntu, etc.
