Ubuntu Linux Disk Encryption Benchmarks

[ Thanks to Michael Larabel for this

“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…”
