Ubuntu 32-bit, 32-bit PAE, 64-bit Benchmarks

Coming up in our forums was a testing request to compare the performance of Linux between using 32-bit, 32-bit PAE, and 64-bit kernels. This is coming after Linus Torvalds has spoke of 25% performance differences between kernels using CONFIG_HIGHMEM4G and those without this option that allows 32-bit builds to address up to 4GB of physical RAM on a system. We decided to compare the performance of the 32-bit, 32-bit PAE, and 64-bit kernels on a modern desktop system and here are the results.

Ubuntu 10.04 Already Shortens The Boot Time

Ubuntu 10.04 Alpha 1 was released last week and while it did not bring any major features yet for this Long-Term Support release of Ubuntu Linux to be released in April of 2010, it began to introduce some underlying changes like the switch to the Linux 2.6.32 kernel, X Server 1.7, and the complete removal of HAL. Our early benchmarks of Ubuntu 10.04 show that there are some negative performance regressions right off the bat, but that is from within the Linux desktop. One area that Canonical is focusing upon in particular with Ubuntu 10.04 LTS is speeding up the boot process, so we decided to provide some benchmarks there too.

Ubuntu 10.04 Is Off To A Poor Performance Start

Tomorrow will mark the first alpha release of Ubuntu 10.04, and while there is still a long journey ahead for this Long-Term Support release before it officially makes its debut in April, we could not pass up the opportunity to provide some early benchmarks of the Lucid Lynx. Ubuntu 10.04 LTS has already pulled in X.Org 7.5 with X Server 1.7 and other updated graphics packages along with the Linux 2.6.32 kernel that it will be using in the final build, which already presents some core differences from the current stable release, Ubuntu 9.10.

FreeBSD 8.0 Benchmarked Against Linux, OpenSolaris

With the stable release of FreeBSD 8.0 arriving last week we finally were able to put it up on the test bench and give it a thorough look over with the Phoronix Test Suite. We compared the FreeBSD 8.0 performance between it and the earlier FreeBSD 7.2 release along with Fedora 12 and Ubuntu 9.10 on the Linux side and then the OpenSolaris 2010.02 b127 snapshot on the Sun OS side.

Chromium OS, Moblin, Ubuntu Netbook Remix Benchmarks

Intel released Moblin 2.1 earlier this month, Canonical released Ubuntu Netbook Remix 9.10 late last month, and various other vendors have offered up their fall distribution refreshes too. Oh yeah, and Google just released the Chromium OS source code a few days ago! With all of the netbook-focused distribution updates, we found it time to run an onslaught of new benchmarks, comparing some of the leaders in this field along with running a couple full-blown desktop distributions for this round of Linux netbook benchmarking. Here are our benchmarks, including the world's first look at the Chromium OS (Chrome OS) system performance from the latest development build. Covered is everything from the video playback performance to encoding to battery power consumption and CPU/memory usage tests.

Mac OS X 10.6.2 vs. Ubuntu 9.10 Benchmarks

Back in August upon the launch of Apple's Snow Leopard we delivered benchmarks comparing Mac OS X 10.5 and Mac OS X 10.6 along with initial benchmarks of how Ubuntu 9.10 was running against Mac OS X 10.6. Since that time though Ubuntu 9.10 has been officially released with various changes since last August and Apple has issued two point releases for Snow Leopard, now putting it at version 10.6.2. As we await the release of FreeBSD 8.0 to deliver a larger operating system comparison, we have carried out a fresh round of tests comparing Mac OS X 10.6.2 and Ubuntu 9.10 (both x86 and x86_64 editions) under a variety of tests.

Fedora 12 vs. Ubuntu 9.10 Benchmarks

Canonical released Ubuntu 9.10 last week, which introduced the Ubuntu Software Center and brought a wide variety of other improvements, while Red Hat is scheduled to release Fedora 12 in two weeks. With the impending release and the current development freeze, we took the compose release candidate for Fedora 12 x86_64 and have looked at how its performance compares to Ubuntu 9.10. In this article are our results, which actually show some rather large differences between Fedora and Ubuntu when it comes to the speed of the Linux desktop.

CentOS 5.4 vs. OpenSuSE 11.2 vs. Ubuntu 9.10 Benchmarks

With the release of CentOS 5.4 last month to bring this community enterprise operating system on par with Red Hat Enterprise Linux 5.4, we decided it was a good time to see how the server / workstation performance between this new CentOS release compares to that of Ubuntu 9.10, which was released last week, and also how it performs up against the release candidate of OpenSuSE 11.2. In this article are these benchmarks.

Running Ubuntu 9.10 With Older PC Hardware

Last week we looked at the Ubuntu 9.10 netbook performance with two Atom-powered netbooks comparing the Karmic Koala numbers against that of Ubuntu 9.04. For the most part, Ubuntu 9.10 offered better performance over its predecessor, but there were a few performance drops in different areas. With our netbook results out of the way, next up we looked at how Ubuntu 9.10 is running with older PC hardware. For the testing in this article we pulled out an aging laptop and ran a set of tests across Ubuntu 8.04.3 LTS, Ubuntu 8.10, Ubuntu 9.04, and the latest Ubuntu 9.10 snapshot.

Ubuntu 9.10 Netbook Performance

There is just one week left until Ubuntu 9.10 "Karmic Koala" will be released, but is it worth the upgrade if you are running a netbook? From our testing of the development releases, it is most certainly worth the upgrade, especially when compared to Ubuntu 9.04 with its buggy Intel driver stack that caused many problems for Atom netbook users. Ubuntu 9.10 brings many usability improvements to the Linux desktop, various new packages, and the overall system performance has improved too. We have ran a set of benchmarks on both a Dell Inspiron Mini 9 and Samsung NC10 under Ubuntu 9.04 and 9.10 to illustrate the performance gains along with a few regressions.
