i need high speed disk encryption (many disks running in parallel, lots of
data movement). i have processor with AES-NI.
geli give 150MB/s performance (tested from/to md ramdisk) using default
and recommended AES-XTS
and ca 400MB/s read and 700MB/s write using AES-CBC.
I'm not cryptography expert, is CBC somehow "less secure", and if so is it
really a problem?
