Introduced in Ubuntu 7.10 was install-time encryption support where using the alternate installer one can fully encrypt their disk in an LVM using dm-crypt. Unfortunately, the Ubiquity installer in Ubuntu 8.04 continues to lack LVM and encryption support, but using Ubuntu 8.04 Alpha 6 we have looked at the performance cost of this encrypted configuration on Ubuntu Linux. Rather than looking directly at the disk read/write overhead caused by the encryption process, we have provided some benchmarks to see how the real-world performance is impacted in both gaming and other desktop tasks.
One reason most users don't encrypt their private information is that it takes too long. Checkout these benchmarks of encrypting an entire hard disk, you may be surprised.
