Hi all, Thanks for the bug report.
Okay I've tracked this down. It helped quite a bit to see that it's mostly Atom processors (eee pc's, and netbooks). This is totally a function of eCryptfs' key strengthening mechanism. For more information about key strengthening, see: * http://en.wikipedia.org/wiki/Key_strengthening The goal here is to make your eCryptfs keys as strong as possible. In the course of generating your fekek (file encryption key encryption key -- see the ecryptfs source code for more details), we perform a has iterative sha512 hash ~65,000 times. This is a non-trivial operation, and it's intended to make brute force attacks against your passphrases 65,000 times harder. While many desktop/laptop/server CPU's can do this key strengthening in about ~1 second, it's taking a bit longer on lower power processors. Unfortunately, this is not something we're going to be able to solve without breaking the ABI/API of eCryptfs. We would need two different versions--a weak-key and a normal key mode. I doubt we're going to solve this any time soon. I'm going to have to mark this "won't fix" for now.
