Because if you do not use the latest machines (e.g. only=20 1 GHz CPU), you get, with cheap hard disks, 42 MB/s without encryption=20 but only 12 MB/s with aes-cbc-essiv:sha256 (using dm-crypt). Thus,=20 encryption seriously sacrifies performance. If you could limit=20 performance-sacrificing to data which is really important (say: /home or=20 /etc, but not /usr or /bin), performance would suffer less. Encryption=20 should be orthogonal to the volume|partition the data is stored on. So=20 I'm looking forward to (transparent) file level encryption becoming=20 usable. :-) > only compression (still not > for product using).
