Revisiting Linux Part 1: A Look at Ubuntu 8.04

Browser & Video Benchmarks
Next up we have our full suite of benchmarks for Firefox, along with a look at video playback performance.
As we discussed in our look at Firefox, the Linux version of Firefox is not compiled with profile guided optimizations, and as a result it underperforms the Windows version in CPU-heavy tasks such as Google’s V8 Javascript benchmark. Running the Windows version under Wine closes this gap, however it’s a limited solution since there are other performance problems (mainly with Flash) in that configuration.
Speaking of Flash, we mentioned previously that it’s slower under Ubuntu (and virtually every other OS) than it is under Windows. This is one of the worst case scenarios, and as GUIMark is capped at 60fps it may actually be worse if we could go higher.
For another look, here’s the CPU usage of Firefox while watching an HD YouTube video. Ubuntu once again underperforms compared to Windows, but not by nearly as much as the worst-case scenario.
In our page loading tests however, this difference melts away. The total loading time of our 4 pages is 12 seconds under both Ubuntu and Vista.
Finally we have VLC as our Linux video playback benchmark. While VLC is not the default media player for Ubuntu, we’re using it instead of Tote due to the fact that it’s cross-platform. Here we’re taking a look at a 30 second section of a 720P H.264 encoded movie.
There’s an interesting phenomena here with respect to CPU usage. VLC uses roughly the same amount of CPU time on both operating systems, however we caught Ubuntu’s X server eating up additional CPU time on Ubuntu, while Windows’ Desktop Window Manager did not move. We’re not entirely sure what’s going on, but it looks like X needs to burn extra CPU time on video playback.

That is exactly how the usability tests are performed. Developer asks Mom "can you change the background" then records what they dofepple - Friday, August 28, 2009 - link
So i tried to find some links about this relating to gnome, but only got some pretty old ones. There are other methods they are using as well, like the 100 paper cuts idea. honestly have a look around and you'll see how much of a focus it is, particularly with ubuntuap90033 - Friday, August 28, 2009 - link
Face it, Linux is still back in Windows 2000 days. Try getting SLI working, 1080P working right, games working. IT IS Way to much trouble and damn near impossible for regular users. In Windows or Mac its next to no work and very little issue. Wake up guys, Linux has Potential but thats it. BECAUSE those who advocate it spend so much energy defending what is "easy" to them when they ought to use that energy making it ACTUALLY easy and USER USER USER USER (DO YOU UNDERSTAND THIS WORD?) FRIENDLY... NOT PROGRAMMER FRIENDLY...newend - Wednesday, September 2, 2009 - link
All of the things you mention are probably not that easy for grandma to do either. People thrive on saying it's so hard to do things in Linux, but I think it's generally not intuitive to use most computer systems. Imagine if you had no exposure to computers how difficult any system would be. A few years ago a friend of mine wanted me to install some software on her Mac. I had no idea how to do it. I've been using computers since I was 5 years old, but had to google for information on installing software.I actually think that Yum/Apt repos actually make it significantly easier to install software. The other day I wanted an application to take a photo with my webcam. I simply did a search "yum search webcam" and looked at the descriptions of included software and found Cheese which did exactly what I wanted.
When you know exactly what you want, and it's not available in the repos you use, I agree it is more difficult to get it installed. Still with both Red Hat/Fedora and Debian/Ubuntu, you can do an install by downloading a package file. This doesn't get you the benefit of automatic updates, but it's just as easy to install as an MSI file.

Well maybe they would want '1080p' but I'm not sure how that could be a problem unless you have some strange hardware that requires a specific driver... like another OS sometime needs you to go to a manufacturers website ;)Penti - Tuesday, September 1, 2009 - link
Installing nVidia drivers and XBMC or mplayer isn't that hard.But keep in mind there is only homebrew codecs on Linux which OEMs like Dell can never ship with there computers and has limited support of proprietary formats such as BD. It's the same codecs as ffdshow, or as in XBMC or VLC on Windows. What's lacking is a PowerDVD with BD support. w32codecs is also available for gstreamer, giving alternative support for WMV and such. Installing ubuntu-restricted-extras is essentially the only thing you need for it to work in Totem if you don't need/have VDPAU support. XBMC is definitively a decent platform to playback warez. You need to rip blurays to be able to play them back at all though. But an Ion is definitively powerful enough for 1080p h264 under linux. But because all that software contains unlicensed patented codecs Canonical don't officially support any of it. So it won't work on ubuntu OOB. Codecs aren't free.

Thing is, 'regular users' dont care about SLI, 1080P and Windows Games... "where is the browser/word processor/email?" :)CastleFox - Friday, April 9, 2010 - link
Great review. Thank you for reviewing 8.04 LTS Please review 10.04 when it comes out. I am interested to see if they software center has changed the authors opinions.tiffanyrose - Wednesday, June 30, 2010 - link
