Hi Gilad,
I've noticed CCREE is used with a LUKS-formatted disk, so I did some small
performance benchmarks. The disk is an old 160 GiB SATA hard drive,
connected to either Salvator-XS (R-Car H3 ES2.0) or Koelsch (R-Car M2-W).
hdparm -t /dev/sda (unencrypted data): 62 MB/s (both systems)
hdparm -t /dev/dm-0 (encrypted data, LUKS AES):
salvator-xs (CCREE): 15 MB/s
salvator-xs (SW): 62 MB/s
koelsch (SW): 47 MB/s
I'm a bit disappointment by the results when using crypto acceleration.
Apparently the in-kernel optimized arm64 implementation can decrypt at
raw read speed, while CCREE can't keep up.
Is this expected, and in line with your experiences?
Thanks!
Gr{oetje,eeting}s,
Geert
