Hi everyone,
I performed the tests again (twice for each test) but this time I
formatted the LUKS partition using:
cryptsetup luksFormat -c aes-xts-plain -s 256 -h ripemd160 /dev/sdd1
…so that I was more _similar_ to the TrueCrypt setup. Also, between
each test I run:
echo 3 > /proc/sys/vm/drop_caches
Here are the new results for the same payload (143 GB of data):
### TRUECRYPT ####
1st round:
real 105m39.547s
user 28m17.667s
sys 42m25.300s
2nd round:
real 105m40.271s
user 28m21.893s
sys 42m19.672s
### LUKS ###
1st round:
real 104m33.901s
user 27m41.362s
sys 41m0.339s
2nd round:
real 104m44.913s
user 27m42.364s
sys 40m57.655s
Now as you may see, LUKS is roughly around 1 minute ahead (sytem-time)
compared to TrueCrypt. It appears the change in cipher operation mode
definitely affected the results (thing I should have done on the first
place).
Cheers and thank your for the feedback!
