Protip: If you have the LUKS/dm-crypt tools installed, there is a benchmark tool that comes with it for checking your performance of different algorithms per the Linux kernel crypto API, by simply invoking cryptsetup benchmark. I just wish it also benchmarked some newer ciphers as well, like those used in WireGuard. Some examples of numbers:
