Hello,
I'm new to this list and ecryptfs, but have been poking around with it for a
few weeks now. I wanted to introduce myself and also share some observations
from a user perspective.
I'm using a dual xeon processor running Fedora7 in a desktop role (KDE). I
created a 1.2GB file to get an idea of how long it would take to write/read
using ecryptfs vs non-ecryptfs on an ext3 file system. I ran multiple
iterations of cp() and dd() using both encfs and ecryptfs, and came up with
the following results using time(1). The timing differences I'm getting
between encfs and ecryptfs surprised me since in a previous posting I recall
Mike saying that he expected ecryptfs to be a better performer than encfs, so
I was hoping someone could comment on them.
WRITE 1.2GB file on ext3 file system

sys: 0m5.559s
using-ecryptfs on ext3
real: 2m18.746s

sys: 0m26.669s
using-encfs on ext3

user: 0m0.150s
sys: 0m6.318s
Regarding the ecryptfs-manager, I've noticed that when looping through the
menu to create multiple keys, the "key type" is displayed multiple times.
Shouldn't "openssl" be displayed only once regardless of how many times you
loop through the menu? Or is this expected behavior? (sorry if this is a
known issue) I've included a log below to demonstrate the looping output.
