Back in December we looked at the initial Ubuntu 8.04 Alpha 2 performance by comparing it to Ubuntu 7.10. In that article we had found the performance between the two releases to be roughly the same. Now that we're nearing an end in this development cycle as Ubuntu 8.04 LTS (Hardy Heron) will be released later this month, we've ran a new set of benchmarks comparing the latest Ubuntu 8.04 packages to the previous Gutsy Gibbon release.
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.
In a previous article, I talked about using
shred to securely delete files. Now we’ll delve into using encrypted volumes in Linux to secure our data in the first place, so that we don’t need to use programs like
shred. Along the way, we’ll benchmark the raw performance of an encrypted volume and compare the results to an unencrypted volume and see just what kind of real world compromises we see.
Ubuntu 8.04 Alpha 2 is due out tomorrow, and while we'll have more extensive testing as the Hardy Heron release nears in April, today we are publishing our first -- very initial -- benchmarks of Ubuntu 8.04 using the 12-19-2007 daily build and comparing these results to Ubuntu 7.10 Gutsy Gibbon. These tests are focused upon OpenGL gaming, encoding, disk, and memory performance.
