Filesystem is irrelevant here. Encryption is done by LUKS, which is a layer between raw block device and filesystem.
It depends on what you are measuring.
The time until grub says "Slot 0 opened" (or similar) involves mostly encryption. The time from there until it displays the menu involves negotiating the file system.
In my experience, the second time (the time for the menu to display) is longer than the time for the basic crypto (I'm not counting the time it takes to type in the encryption key).
True, but I'd only expect this to be significant on large Btrfs file systems. There is a slow mount time optimization in more recent kernels, no idea if that would be useful or possible in the GRUB btrfs code. -- Chris Murphy -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org
