Slow mount time #48

Open hholst80 opened 8 years ago

I am using Windows 10 64-bit and I am experiencing slow mount times.

The 100 MiB block file blkdev.vol was created in Debian Testing using

# cryptsetup -v --cipher aes-xts-plain64 --key-size 256 --hash sha256 --iter-time 2000 --use-urandom --verify-passphrase luksFormat blkdev.vol

(i.e., the default luksFormat options)

It takes 5-10 seconds to mount the volume in Windows.

LibreCrypt is approximately half the speed of some other crypto products because it uses an old version of the crypto library, which doesn't use hardware acceleration. This only applies to operations dominated by CPU, like mounting a volume, not reading and writing. If possible, could you please check the time to mount using cryptsetup on the same hardware?
