Revisiting Linux Part 1: A Look at Ubuntu 8.04

File/Networking Performance
Finally we have file and networking performance. As Ubuntu uses a different file system (ext3 versus Windows’ NTFS) there’s the potential for some significant differences here.
Starting with file performance, we will be using a collection of roughly 1500 files, totaling 380MB.
Even after SP1, file performance has long been a thron in the side of Vista. Here it manages an embarrassing loss to Ubuntu, taking over 50% longer to make a copy of the same folder.
Looking at ZIP compression times, it’s an even larger gap. Vista needs 75% longer to compress the same folder. While compression can be CPU bound, looking at our data this specific test is largely I/O bound. We’ve already established at Windows’ built-in ZIP abilities are pretty bad, but we’ve never figured out why this is.
Decompression is even worse for Windows. It takes nearly 4 times as long to decompress the same archive. It’s not even a contest – Ubuntu wins, if only because it’s the only competent operating system out of the two.
Meanwhile in our network copy tests, we are copying that folder to a server running Windows Server 2003. This gives Windows an advantage since we’re using SMB, but since SMB is the predominant protocol for consumer file server gear, it’s a fair test of such use.
Here it’s nearly a dead heat. Both Ubuntu and Vista need just as long to copy our file collection to the server, meanwhile Windows needs a bit less time to copy that same folder off of the server.
Switching gears, using a 2.6GB ISO we see a clear performance difference. In both copying to and from the server, Ubuntu needs at least 50% longer. Since this test isn’t using a lot of CPU time, our best guess is that Windows is doing some buffering that Ubuntu doesn’t get to do. The transfer rates for Linux are below what the hard drives on either end can manage.
Ultimately for users with lots of local storage, Ubuntu appears to outshine Vista. But for users with lots of remote storage (e.g. a NAS), Vista outshines Ubuntu.
Finally we have the amount of time it takes to start up each operating system, another disk-bound test. Vista is not something I would consider particularly speedy, so I’m a bit surprised that Ubuntu did not manage to outperform it here. The 2 second difference is measurable, but small enough that it won’t make any real impact.

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
