I use LVM and LUKS too. While I haven't encrypted /boot (due to using UEFI) I do have full disk encryption on the remaining disks. The longest delay is mounting the spinning disks but overall after I enter the password boot takes less than 30 seconds... I would recommend to check the output of the following commands: systemd-analye systemd-analyze critical-chain These will output the boot times (firmware, bootloader, kernel, initrd, userspace) and the service chain that took the longest during boot.
