I can only speak to loop-AES, not crypto loop, which for me (3Ghz P4) encrypts and decrypts at over 100MB/s in single-key mode, and about 70MB/s in multi-key mode. So the answer for me is not at all, as long as the processor isn't busy doing something else. Assuming that your loop file is bigger than the amount of memory you have installed, You can test it with something like: # time dd if=mystuff.aes of=/dev/null bs=64k # time dd if=/dev/loop0 of=/dev/null bs=64k Take an average of 3-4 runs each, ignoring the first result. -Richard -- gentoo-user@gentoo.org mailing list
