Ubuntu 9.04 Receives EXT4 Support

With the EXT4 file-system having been stabilized with the Linux 2.6.28 kernel, the Ubuntu developers are preparing to adopt this evolutionary Linux file-system update. EXT4 will not replace EXT3 as the default file-system until at least Ubuntu 9.10, but as of yesterday, Ubuntu 9.04 now has install-time support for EXT4. In this article we are looking at the EXT4 support within Ubuntu as well as providing a few Linux file-system benchmarks from a netbook-embedded solid-state drive. In this article we have published Ubuntu benchmarks of EXT4, EXT3, XFS, JFS, and ReiserFS file-systems.

Ubuntu 9.04 Home Encryption Performance

One of the exciting features that is being worked on for Ubuntu 9.04 is encrypted home directories. What this means is that at install-time for either the LiveCD or server installation (or at a point later on when creating additional user accounts), the administrator can opt to have the user's home directory encrypted. This is a step-down from the Ubuntu 7.10 install-time encryption that would encrypt the entire hard drive and just not the user's home directory, but alas, that comes with performance consequences. At the request of Canonical, we have carried out a few benchmarks showing what effect the Ubuntu 9.04 home encryption feature has on the system's overall performance.

OpenSolaris 2008.05 vs. OpenSolaris 2008.11 Benchmarks

Seven months after the release of OpenSolaris 2008.05 (a.k.a. Project Indiana) its successor was finally released earlier this week. OpenSolaris 2008.11 was released on Tuesday with many updated packages and new features. To see how this new work has affected the performance of Sun's OpenSolaris operating system, we have benchmarked both releases through some different tests.

Fedora 10 vs. Ubuntu 8.10 Benchmarks

With Fedora 10 finally entering the world earlier this week, we have performed benchmarks comparing the performance of Ubuntu 8.10 and Fedora 10. In our testing we used both the 32-bit and 64-bit builds of each distribution and then ran a series of automated tests through the Phoronix Test Suite.

Fedora 10 Cambridge Released

Following several months in development, Red Hat has just released Fedora 10 (codenamed Cambridge). A number of new Red Hat innovations can be found in this release, such as Plymouth, and there are many updated packages such as those from X.Org and the Linux kernel. In this article are some screenshots from Fedora 10 final along with some of the other features that make up the tenth release of this very popular Linux distribution.

Ubuntu vs. OpenSolaris vs. FreeBSD Benchmarks

Over the past few weeks we have been providing several in-depth articles looking at the performance of Ubuntu Linux. We had begun by providing Ubuntu 7.04 to 8.10 benchmarks and had found the performance of this popular Linux distribution to become slower with time and that article was followed up with Mac OS X 10.5 vs. Ubuntu 8.10 benchmarks and other articles looking at the state of Ubuntu's performance. In this article, we are now comparing the 64-bit performance of Ubuntu 8.10 against the latest test releases of OpenSolaris 2008.11 and FreeBSD 7.1.

Ubuntu 9.04 "Jaunty Jackalope" Alpha 1

It's arriving two days late, but the first alpha release for Ubuntu 9.04 is now available. While there are some updated packages, to the normal desktop user there really isn't much to note in the way of changes. However, to learn more about the features that will be introduced in future development releases of Ubuntu 9.04, checkout our Exciting Features For Ubuntu 9.04 article.

Exciting Features For Ubuntu 9.04

If all goes according to plan, the first alpha release for Ubuntu 9.04 (the Jaunty Jackalope) will be released tomorrow. It's not even been one month since the release of Ubuntu 8.10, but this first alpha release will show early signs of what we can expect to see in this next Canonical-sponsored release -- albeit many of the features are still in planning. In this article we will provide a glimpse at what Ubuntu 9.04 should hold in store to captivate Linux desktop users.

Mac OS X 10.5 vs. Ubuntu 8.10 Benchmarks

Last week we published Ubuntu 7.04 to 8.10 benchmarks from a Lenovo ThinkPad T60 and had found Ubuntu's performance degraded peculiarly over the past year and a half. We then published Fedora 7 to 10 benchmarks covering the same time-frame and from the same exact Intel notebook computer, but the newer releases of Fedora were only marginally slower in a few tests. In our performance exploration of Ubuntu we now have additional tests to publish this morning. This time around we're switching out the hardware we're testing on to Intel's newer Core 2 series and we're comparing the performance of the x86 and x86_64 editions of Ubuntu 8.10 against Apple's Mac OS X 10.5.5 operating system.

One Year With OpenSolaris Binary Releases

It was one year ago to the day that the first developer preview of Sun Microsystem's Project Indiana was released and was called OpenSolaris, the same name that Sun had been using for their open-source Solaris code repository. Since then we have had the official release of OpenSolaris 2008.05 and version 2008.11 of OpenSolaris has been under development but is scheduled to be officially released in November.
