CPU Benchmarks

We’ll start our short look at Ubuntu’s performance with our CPU intensive benchmarks. Up first is SuperPi, a single-threaded pi-calculating benchmark. Here we time how long it takes to calculate Pi to 1 million digits.

We ran this test several times more than usual just to make sure we weren’t seeing any kind of error. The Linux version of SuperPi really is about 30% faster than the Vista version. Keep this in mind, this will be an important point later.

Meanwhile the situation for LAME is inverted. Vista outscores the Linux version by nearly 20%.

Using the cross-platform X264-based Handbreak for our video encoding test, Vista once again pulls ahead of Linux.

Once more Vista is ahead by a large margin.

From what we can tell, there’s little-if-any innate performance advantage to Vista or Linux in these benchmarks. Our working theory is that the performance difference comes down to the compiler used. Many Linux applications are compiled with GCC, while for Windows it’s either the Visual Studio compiler, or Intel’s own compiler (which is also available for Linux). There’s also a matter of compiler settings, as we saw in our quick breakout of Firefox benchmarks.

Meanwhile SuperPi uses a lot of hand-rolled code, although we’re still not sure why it’s outperforming Vista on Linux by as much as it is.

To shed a little more light on this idea of compiler performance, we have a few benchmarks of Windows application performance under Ubuntu through Wine.

Here we see a most amazing thing: Ubuntu is outperforming Windows at running Windows applications! As we’ve removed the influence of compilers the Photoshop results are particularly interesting. From what we can tell it’s normally as fast under Linux as it is Vista, however there seems to be a short gap of low-CPU usage when running it under Vista that doesn’t occur when running it under Ubuntu. As a result Ubuntu finishes a few seconds earlier.

There are a number of conditional cases that mean that applications running under Wine don’t always match or beat Windows performance, but in our tests there’s no performance hit to using Wine to run Windows applications.

These results also lend a great deal of support to the idea that there’s a significant difference in performance between the two operating systems due to their compilers. This goes particularly for the LAME benchmark, where the performance gap melts away under Wine. This is something we’re going to have to look in to in the future.

    I see you shared a lot of the same problems I had with Ubuntu when I first got it. Yeah, it's harder, I won't lie, and it's a pain in the ass when it doesn't work. But when it works, you love it, and you feel like more of a man. I use it for my web server, runs very nicely.

    Ubuntu sometimes makes you want to shoot it with a m249, but at other times you feel superior to other users. But that's because you are using the terminal all the time and are actually smart, Mac users just need to be shot in the face for their ignorance.

    I agreed with a lot of what was in this review.

    I think a lot of your problems would have gone away by using the newer versions, though, specifically with the package manager. There's much less need for finding things outside of it when you're using the new versions. Even video drivers can usually be put off for 6 months or so if you're not too cutting edge. Leaving the package manager behind is a pain, though, as you found out. You tried to explain that the LTS version was more comparable to Windows/OSX, but in truth very very few desktop users continue to use it. In fact, I'm not aware of any. It's really only used by companies for work machines who don't want to make large changes every 6 months like home users can.

    MSTT fonts. Good luck trying to get those by default, they're owned by microsoft who is in no mood to simply give them away to their competitors. Installing them is like installing the patent encumbered video codecs - at your own risk, which is minimal as long as you aren't trying to make money off of it.

    It should be mentioned that Red Hat put down some money to buy some nice new fonts a while ago, called Liberation, that are much nicer than the default serif ones this old Ubuntu version was using. Still different than the MS ones, though, which is going to cause some people problems. Also, the font anti-aliasing differences are again due to patents owned by other companies, but there's good news there. They're supposed to expire later this year so better font rendering in Linux should be coming soon! You can already get it working manually, but the distros make it hard to setup.

    You mentioned you chose Ubuntu because it was supposed to be user-friendly, which I regard as one of the more puzzling wide-spread myths that go around. Sure, it's a lot simpler than Debian, or some other choices, but it is definitely NOT the distro to choose if you're looking to avoid the CLI, as you found out.

    On that note, I would HIGHLY encourage you to eventually go back and do another review (part 3?) that uses a KDE based distro. Maybe try out OpenSUSE next fall, for example. Although KDE is going through a bit of a transition now, it's definitely where all the more interesting stuff is going on. As you said, Gnome is a lot like a boring Windows XP environment, which is both a positive and a negative. KDE is quite different, for better or worse, and is worth a look I think. For one thing, that smb://COMPUTERNAME address will work out of the box in KDE apps. If you do try KDE, I highly recommend another distro besides (K)Ubuntu, though, because they simply don't put any resources into their KDE implementation and it shows.

    Ubuntu KDE has more options to play with that are missing in gnome (but gnome top is far better then KDE top, long time i used linux its task monitor, Linux verson of windows XP task manager but only the process page but very detailed)

    Ubuntu should be easy to use but it lacks the easy install for drivers and Still does not offer Fail save VGA mode if X windows fails to start your stuck with an command line, it should try an second time but in save mode vga but it does not

    Thought I'd mention a linux specific site Phoronix has an "Open Letter to Tech Review sites" (http://www.phoronix.com/scan.php?page=article&...">http://www.phoronix.com/scan.php?page=article&....

    You mentioned linux on Netbooks, and thought I would mention that I found Moblin(www.moblin.org) from Intel very impressive. It's still in beta and a little rough around the edges, but it boots faster than xp resumes from hibernate, around 15sec from bios screen and the UI is designed around small screens. After using it for a few hours and then installing Windows 7, I immediately missed how well Moblin was optimized for the lowres small screen. I had to install W7 because the ath9k kernel module drivers are unstable in Moblin, if not for this I would probably keep it as the primary OS on my netbook.

    I ve been using Ubuntu 9.0 for a year with my Dell notebook and i love it, I dont see limitations in my work, the only problem is my company doesn't allow it in the network but is my OS in the house
  • Eeqmcsq - Wednesday, August 26, 2009 - link

    I'm still reading it, but on my xubuntu 8.04, my firefox is located in /usr/bin/firefox. Most apps are under /usr/bin.

    Also, the directory structure is definitely VERY different from Windows. One main difference is that everything that belongs to the user is supposed to be under /home. Everything that belongs to the "system" is everywhere else. I think the theory is that the user stuff is "sandboxed" in /home, so he doesn't mess things up in the system for everyone else.

    You have the same in Windows under %SystemDrive%\Documents and Settings\user Although many settings are stored in the register (which can be said to be the equivalent of /etc). It's however there programs like Firefox saves it settings and where you have your My Documents and tempfiles.

    * %SystemDrive% is a variable and substitute for your systems drive letter on which Windows is installed which can be something other then C:.

    On the normal Ubuntu install, the /usr/bin/firefox is actually a symlink that points to the firefox install in /usr/lib :)
  • ioannis - Wednesday, August 26, 2009 - link

    the question is, who cares where firefox or any other application's binary is installed? It's not as if you'll go searching for it to run it. They are on your execution 'PATH', which means you can just press ctrl+F2 and type their name, or a terminal, or access them from the application menu.

    My favourite way is to use something like gnome-go (or krunner in Kubuntu)

    PS: yes, all package manager provided application have their binaries in /usr/bin and most user build ones go in /usr/local/bin by default, which is also in your $PATH.

    As a developer that has to deal with custom paths or managing symlinks in default paths, I can say I do care where binaries are located ;)
