Hi, I have been using full-disk encryption on my laptop for several years over several laptops. My current one is a Dell Latitude E6500 with a 2.66GHz Core2Duo P9600 with 4GB of RAM, and the lag from encryption is not noticeable.
The way I did it was from the installer. I created a separate (and unencrypted) /boot, a swap and a large partition for encryption. Within the encrypted partition, I created an LVM volume group and created my filesystems within. I note, at this point, that if you want added security, you create your /boot on a USB thumb drive. This way, the machine will not even boot without this drive. I would also add that reiserfs3 had issues with multicore. I noticed that every time I rebooted my workstation, it would replay the journal, whether or not it had unmounted the filesystems cleanly. I found an article stating that it was due to reiserfs not playing nicely with the multiple cores, so you may want to consider another filesystem. I ended up going with ext4 until I get a chance to get familiar with btrfs or one of the other newer filesystems. --b On Sat, Nov 26, 2011 at 12:15 AM, J.
