    Phoronix: 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.

    Didn't they say they wanted to replace some parts of the Xorg stack?

    Also I can't see them basing Chrome OS on Ubuntu in the future...

      I downloaded a VMware image of Chromium OS a couple of days ago, and ran it in VirtualBox. It boots very fast but the Chrome browser was the only app I could use, so I don't know how exactly you got to remount the root file-system. I got bored pretty quickly by it.

        lol fedora's screenshot with gnome looks so bad compared to the opensuse kde4 one.

          Fedora's GNOME got to be the worst (looking) out there. I cringe every time I see a default GNOME Fedora desktop.

            disappointing comparison....

            *** DISCLAIMER: I work for Intel, on Moblin. ***

            I find it hard to believe that this review largely focussed on generic linux desktop performance while the test subjects where all _netbook_ specific OS spins, tested on a typical netbook platform.

            For the next time, take a look at the following instead:

            - boot times
            - suspend/resume times
            - total battery life while idle
            - battery life while performing netbook-typical tasks, such as:
            + browsing webpages inclusing flash
            + perhaps watching youtube/hulu videos
            + skypeing etc

            encoding x264 is totally irrelevant on any netbook install, and the differences on the 7z encoding could as well have been omitted from the review leaving little meat. The only big difference I can see is due to ext3/4 differences (and then moblin is going to use btrfs in the future as well...)

            all in all, this review IMHO lacks quite some substance... something that won't help the targeted netbook audience nor me as a developer.

            sure, phoronix is read by geeks (guilty here), but taking openarena fps as a significant test is dubious on any netbook platform unless you measure power consumption at the same time (and then the result may be skewed by the OS sacrificing FPS for power).

            I know phoronix can do a lot better!

              The videos about Chromium OS say they want to avoid the double initialization of hardware (the BIOS does it, then the kernel does all over again).

              That's probably going to require something like coreboot. (Or maybe EFI... I don't know anything about EFI - maybe it can skip some of the stuff BIOS does?)

              So even though the vmware image you tried boots fast, it probably still doesn't do justice to the boot speed that should result from what they're planning.

                Tell me who is to blame for the extremely bad moblin performance with vbox? And why is the generated filesystem so extremely small, thats without any reason as it only restricts the size to install extra software - it is not enough for vbox addons. With fedora it does work using:

                http://kanotix.com/files/install-vbox-addons.sh

                So why not in Moblin which is definitely a fedora clone. I know there are some extra depends needed to install, but without more space to install it is not that easy.

                  CPU usage allright with openSuse

                  I don't think it is too surprising that suse utilizes its cpu most. The target with battery and cpu-usage is - (sometimes) - to use the cpu as much as possible but less than 100%. So if you slow it down, the percentage will be higher, and you save energy while at it.

                    long (technical) answer:

                    moblin is developed for netbooks, not for enthusiasts who want to run it inside a VM. Developing a netbook OS and making it run well in a VM as well is virtually impossible, since only virtualbox currently has OpenGL passthru, but it is completely dependent on the compatibility between the hosts' OpenGL capabilities, vbox's mapping to, and the client's requirements from the 3D hardware. Since moblin's UI requires hardware accelerated OpenGL (you can't make a decent UI nowadays without 3D and composite support...), it's pretty unlikely that you'll get anywhere near the native performance under any VM implementation, and vbox's OpenGL passthru isn't mature enough (or can't ever be...) to fix that hole.

                    People keep assuming that they can just test-drive every OS inside a VM and get 100% of the look/feel/performance of how it works on a real device, but in Moblin's case that is a totally wrong perception.


                    And why is the generated filesystem so extremely small, thats without any reason as it only restricts the size to install extra software
                    I'm not sure what you are referring to here, care to file a bugreport with numbers and debug output on bugzilla.moblin.org?

                      An interesting read. Though IMO all in all, every distro was quite the same.

                        I think the review is totally unfair!!!!

                        All OS accept ext4 or ext3 FS, so, why not to run all test on the same filesystem, this way results are not filesystem dependant.

                        Yeah, i know that on some distributions you can't choose ext4 on installation process. But i think this is a feature not implemented yet, with a little work you can convert ext3 to ext4 and run the test.

                          Yes, most glaring was that ext4 performed better than etx3

                            Thanks for this test, and of course as the Moblin depeloper says, some more tests may be added
                            boot times
                            - suspend/resume times
                            - total battery life while idle
                            - battery life while performing netbook-typical tasks, such as:
                            + browsing webpages inclusing flash
                            + perhaps watching youtube/hulu videos
                            + skypeing

                            I think it is a good idea to add this tests to Phoronix test suite

                              That's not correct. Vbox is even able to handle Compiz for Linux guest (with Xserver 1.5+). What i mean is what you see when you do

                              df -h

                              Then you will notice that no aufs overlay is used which is only restricted by tmpfs but some other way which relies on a creation time settings. Best is to compare that against Fedora.

                              Also i would like to know how to stop Moblin from tring to start X as user. That only works with Intel onboard. I don't know why it is so impossible hard to implement at least a working VESA fallback, it does not matter if you can not do fancy 3d stuff with it which i don't need anyway. Of course it would be nice to get vbox addons installed later in order to get mouse integration, screen resizing and if needed even 3d.
