Ubuntu – Long Term Support

One item of particular interest with Ubuntu is their development schedule. Because a typical Linux distribution is composed of many applications from many different parties, the Ubuntu developers do not directly control or develop a lot of the software included in Ubuntu. Furthermore Ubuntu tries to be a complete desktop environment rather than just an operating system, which means it includes a wider variety of software than what’s found in Windows and Mac OS X.

What this amounts to is that Ubuntu needs to both provide future patch support for included applications, and it needs to compensate for the fact that they don’t develop many of these programs. Coupled with this is the fact that 2nd party application development is not necessarily synchronized to Ubuntu’s release schedule and some applications (and the kernel itself) can have a rather rapid development rate.

Trying to deal with all of these factors, Ubuntu has settled on two classes of releases. Every 6 months – in October and April – Ubuntu takes what’s ready and releases a new version of the OS. For 1st party material this is tied with some goal for the release (such as replacing the audio daemon) while for 3rd party software this may be as simple as grabbing the latest version. This puts regular Ubuntu versions in an unusual position when trying to classify them – it’s significantly more than a Mac OS X point update, still more than a Windows service pack, and yet a single release generally encompasses less than a new version of either OS. But at the same time, there’s no guarantee that any given release of Ubuntu won’t break software compatibility or binary driver compatibility, which puts it up there with major OS releases.

Furthermore because of the need to provide security updates for all these different programs in all of these different versions, Ubuntu has a very short support cycle, and in that cycle only bug fixes and security updates will be issued, software is not otherwise changed as it’s intended to represent a stable platform. A regular release is only supported for 1.5 years; which for example means support for 7.10 Gutsy, the immediate predecessor to 8.04 Hardy Heron, expired in April. This pushes new versions of Ubuntu back towards the idea of them being closer to a service pack or a point release. In essence, it’s intended that everyone using regular versions of Ubuntu will stick to a relatively rapid upgrade treadmill.

But this obviously doesn’t work for everyone, which results in there being two classes of Ubuntu. What we’re looking at today, 8.04, is what Ubuntu calls a long term support (LTS) release. Every 2 years a version of Ubuntu is labeled as a LTS release, which entails a much greater effort on the developer’s part to support that edition of the OS. The standard support period is 3 years instead of 1.5 years, and for the server edition of the OS that becomes 5 years.

This makes the LTS releases more comparable to Mac OS X and Windows, both of which have long support periods in excess of 3 years. This is also why we’re starting with a review of Hardy, in spite of it being over a year old now, because it’s the current LTS release. Regular short-support Ubuntu releases have their place, but they are not intended for long-term use. Coming from Windows or Mac OS X, a LTS release is the comparable equivalent.

Operating System Mainstream Support Extended Support
Windows 5 years 5 additional years
Ubuntu 1.5 years None
Ubuntu LTS 3 years None
Mac OS X So long as it's the newest OS So long as it's one version behind

Unfortunately, in spite of the LTS designation, not all of the applications in a LTS release are intended to be used for such a long period of time, or are their developers willing to support them for that length of time. If we take Firefox for example, the last Ubuntu LTS release, 6.06 Dapper, shipped with Firefox 1.5. Mozilla very quickly ended support for Firefox 1.xx after Firefox 2 shipped, and now you can’t even get support for 2.xx now that 3.xx has been out for quite some time. This leaves the Ubuntu developers in charge of supplying security updates for the older versions of Firefox they still support, which while better than the alternative (no security patches) isn’t necessarily a great solution.

The Ubuntu developers have done a good job of staying on top of the matter (they just published a new 1.5 security patch as recently as last month) but it highlights the fact that the Ubuntu developers do not always have the resources to maintain both a stable platform and the necessary security updates. So while an LTS release is supposed to be supported for 3 years, in reality not every component is going to make it that long.

Digging through the bugs list for Dapper and Hardy, I get the impression that these kinds of cracks only occur on less-used software (particularly that which is not part of the default install, such as VLC), so an option for users who need to stick with the base OS for the entire life of a LTS release, but don’t mind upgrading a few applications can go that route and cover all of their bases. Unfortunately this is easier said than done, and we’ll get to why that is when we discuss the package manager.

What this amounts to is that if you’re the kind of person that intends to run a computer and an OS for a very long period of time – say on the scale of XP, which turns 8 this year – Ubuntu likely isn’t a good fit for you.

It’s Secure What’s the Value of Technical Support, Anyhow?

    I concur - while most of the article is quite good, Ryan really seemed to have missed quite a bit here. His analysis of it seemed rather limited if not misleading.

    Not everything *has* to be a package - I have various scripts strewn around, along with Firefox 3.6a1 and a bunch of other things without having them organized properly as .deb's with APT. The packaging system is convenient if you want to use it, but it is not required.

    Additionally, Ryan made it seem as though everything must be installed through Synaptic or Add/Remove and that there where no stand-alone installers along the lines of Windows' .msi files. It's quite easy on Ubuntu to download a .deb file and double-click on it. In fact, it's much simpler then Windows' .msi files - there's no questions or hitting next. You just give it your password and it takes care of everything else.

    The one area I agree with Ryan is that there needs to be an standardized, easy, GUI fashion to add a repository (both the address and key) to APT. I have no problems with doing things like >>/etc/apt/sources.list, but I could see where others may. I suspect this could be done through a .deb, but I've never seen it done that way.

    Something I've been fishing for here and have not yet seen much of are requests for benchmarks. Part 2 is going to be 9.04 (no multi-Linux comparisons at this point, maybe later) and I'd like to know what you guys would like to see with respect to performance.

    We'll have a new i7 rig for 9.04, so I'll be taking a look at a few system level things (e.g. startup time) along side a look at what's new between 8.04 and 9.04. I'll also be taking a quick look at some compiler stuff and GPU-related items.

    Beyond that the board is open. Are there specific performance areas or applications that you guys would like to see(no laptops, please)? We're open to suggestions, so here's your chance to help us build a testing suite for future Linux articles.

    I'd like to see differences between PPD in World Community Grid between various Windows and Linux distros.
    I never really see AT talk about WCG or other distributed computing, but I figure if I'm gonna OC the crap out of my cpu, I might as well put it to good use.

    Cross platform testing is pretty difficult, considering there are a multitude of different apps to accomplish the same task, some faster, some slower. And then there's the compiler optimizations for the same cross platform app as you mentioned in the article. However, I understand that from an end user's perspective, it's all about doing a "task". So just to throw a few ideas out there involving cross platform apps so that it's a bit more comparable...

    - Image or video conversion using GIMP or vlc.
    - Spreadsheet calculations using the Open Office Calc app.
    - Performance tests through VMware.
    - How about something java related? Java compiling, a java pi calculator app, or some other java single/multi threaded test app.
    - Perl or python script tests.
    - FTP transfer tests.
    - 802.11 b/g/whatever wireless transfer tests.
    - Hard drive tests, AHCI. (I read bad things about AMD's AHCI drivers, and that Windows AHCI drivers were OK. What about in Ubuntu?)
    - Linux software RAID vs "motherboard RAID", which is usually only available to Windows.
    - Linux fat32/NTFS format time/read/write tests vs Windows
    - Wasn't there some thread scheduling issues with AMD Cool and Quiet and Windows that dropped AMD's performance? What about in Linux?

    While I'm brainstorming, here's a few tests that's more about functionality and features than performance:
    - bluetooth connectivity, ip over bluetooth, etc
    - printing, detecting local/network printers
    - connected accessories, such as ipods, flash drives, or cameras through usb or firewire
    - detecting computers on the local network (Places -> Network)
    - multi channel audio, multi monitor video

    Just for fun:
    - Find a Windows virus/trojan/whatever that deletes files, unleash it in Ubuntu through Wine, see how much damage it does.

    I know you've said in previous comments that using Phoronix Test Suite for benchmarking different OSes (e.g. Ubuntu vs Vista) won't work because PTS doesn't install in Windows, but you could probably use a list of the available tests/suites in PTS as a place to get ideas for commonly available programs in Windows/OSX/Linux.

    I'm pretty sure that Unigine's Tropics/Sanctuary demos/benchmarks are available in Windows, so those could bench OpenGL/graphics.

    Maybe either UT2004 or some version of Quake or Doom 3 would work as gaming benchmarks. It's all going to be OpenGL stuff, but it's better than nothing. You could also do WoW in Wine, or Eve under Wine to test some game compatibility/performance.

    Once you get VDPAU working, I'd love to see CPU usage comparisons between windows/linux for media playback of H.264 videos. And also, I guess, a test without VDPAU/VAAPI working. Too bad for ATI that XvBA isn't supported yet... might be worth mentioning that in the article.

    You also might want to search around for any available OpenCL demos which exist. Nvidia's newest Linux driver supports OpenCL, so that might give you a common platform/API for programs to test.

    I've often felt that DVD Shrink runs faster in Wine than in Windows, so the time to run a DVD rip would be nice, but might have legal implications.

    Some sort of multitasking benchmark would be nice, but I'm not sure how you'd do it. Yeah, I can see a way of writing a shell script to automatically launch multiple benchmarks simultaneously (and time them all), but the windows side is a little tougher to me (some sort of batch script might work). Web Browsing + File Copy + Transcoding a video (or similar).

    Ooh... Encryption performance benchmarks might be nice. Either a test of how many PGP/GPG signs per second, or copying data between a normal disk partition, and a TrueCrypt partition. The TrueCrypt file copy test would be interesting to me, and would cover both encryption performance and some disk I/O.

    One last suggestion: Folding@Home benchmarks. F@H is available at least in CPU-driven form in Windows/Linux, and there's F@H benchmark methodologies already developed by other sites (e.g. techreport.com's CPU articles).

    Well, that's enough for now. Take or leave the suggestions as you see fit.

    you are out of luck here ... linux does not compare to windows because they are both different architectures. you already did what you could in the article.

    especialy in a binary distribution like Ubuntu, compilation speed tests are meaningless (but Gentoo folks would kiss your feet for that).

    boot up times are also not usefull. the init scripts and even init mechanisms are different from distro to distro.

    compression/filesystem benchmarks are half way usable. on windows you only have NTFS these days. on linux there are like 20 different filesystems that you can use (ext3/4, reiser, jfs and xfs are the most used. also quite many distros offer lvm/evms backends or software raid.

    I do not think there is much benchmarking you can do that will help in linux vs windows, even ubuntu vs windows because the same benchmars will differ between ubuntu versions.

    the only usable types are wine+game vs windows+game, native linux game vs same windows game (mostly limited to unreal and quake angines), some povray/blender tests and application comparisons (like you did with the firefox javascript speed).

    Not really a benchmark per se, but I'd be curious to know how the stereotypes of Windows being bloated and Ubuntu being slim and efficient translate to power consumption. Load and idle would be nice, but if at all possible I’d be much more curious to see a comparison of task energy draw, i.e. not so much how long it takes them to finish various tasks, but how much energy they need to finish them.

    In know that’d be a very difficult test to perform for what will probably be a boring and indeterminate result, but you asked. :)
  • ioannis - Wednesday, August 26, 2009 - link

    is there some kind of cross platform test that can be done to test memory usage? Maybe Firefox on both platforms? not sure.

    By "no laptops", I presume you mean, no battery tests (therefore power and as a consequence, heat). That would have been nice though. Maybe for those looking for a 'quiet' setup.

    but yes, definitely GPU (including video acceleration) and the GCC vs Visual Studio vs Intel compiler arena (along with some technical explanation why there are such huge differences)






  • ParadigmComplex - Wednesday, August 26, 2009 - link

    If you can, find games that are reported to work well under WINE and benchmark those against those running natively in Windows. It'd be interesting to see how the various differences between the two systems, and WINE itself, could effect benchmarks.

    Number 1 use of Ubuntu is probably going to be for netbooks/low end desktops for people who just wanna browse the net.
    In that case, the browsing experience (including flash) should be investigated.
    Boot up time is important.
    Performance with differing memory amounts would be nice to see (say 256MB, 512MB, 1GB, and 2GB or higher). Scaling across cpus would be nice.

    Ubuntu as a programming environment versus windows would be good to see, including available IDEs and compiler and runtime performance.

    Ubuntu as a media server/HTPC would be good to see. Personally, I have my windows box using DAAP shares since Ubuntu interfaces with it much better than Samba. And as an HTPC, XBMC and Boxee are nice, cross-platform apps.

    Finally, how Ubuntu compares for more specific applications. For instance, scientific computing, audio editing, video editing, and image manipulation. Can it (with the addition of apps found through it's add/remove programs app) function well-enough in a variety of areas to be an all-around replacement for OSX or Windows?
    Speedwise, how do GIMP and Photoshop compare doing similar tasks? Is there anything even on par with Windows Movie Maker?
    What's Linux like game wise? Do flash games take a noticeable performance hit? Are the smattering of id software games and quake/super mario bros/tetris/etc clones any good? How does it handle some of the more popular WINE games?
