I followed the guide to the letter, and it all seemed to work wonderfully. Then the pain began when I started to move my files back to the encrypted volume. What a performance killer! It's eating 90% CPU and it takes *forever*, because it keeps 'hanging'. If I switch focus to another window, then kcryptd/0 and kjournald stop working (they are the processes taking 90%). If I shut laptop lid (set to blank screen) then they stop working. If the screensaver activates, then they stop working. When they stop (zero percent CPU) then the disk activity stops as well. When I run scp from a ethernet attached laptop then scp says: ubuntu-7.10-alternate-amd64.iso 86% 684MB 2.9MB/s -stalled- and as you can see by the transfer rate, it is nowhere near the 11MB/s I was getting consistently before encrypting. Is this normal write performance? Can the "terminal loses focus: copy suspends" behaviour be fixed? I have not tested read performance yet, but I expect and hope that it will be more normal. --andrew -- GnuPG Key ID: ECB18ABA Fingerprint: FDF3 91FC F5BC 1164 E217 315E 337E 219B ECB1 8ABA -- GnuPG Key ID: ECB18ABA Fingerprint: FDF3 91FC F5BC 1164 E217 315E 337E 219B ECB1 8ABA
