Is Ubuntu Getting Slower?

An anonymous reader writes "Phoronix has a new article where they provide Ubuntu 7.04, 7.10, 8.04, and 8.10 benchmarks and had ran many tests. In that article, when using an Intel notebook they witness major slowdowns in different areas and ask the question, Is Ubuntu getting slower? From the article: 'A number of significant kernel changes had went on between these Ubuntu Linux releases including the Completely Fair Scheduler, the SLUB allocator, tickless kernel support, etc. We had also repeated many of these tests to confirm we were not experiencing a performance fluke or other issue (even though the Phoronix Test Suite carries out each test in a completely automated and repeatable fashion) but nothing had changed. Ubuntu 7.04 was certainly the Feisty Fawn for performance, but based upon these results perhaps it would be better to call Ubuntu 7.10 the Gooey Gibbon, 8.04 the Hungover Heron, and 8.10 the Idling Ibex.'"

    Let's see how that statement works in this situation:

    It shouldn't be getting slower, but then again, performance isn't the reason Vista exists.

    If you really want performance, run FreeDOS. Otherwise, shut up and get used to progress.

    Were they testing each distribution on exactly the same hardware?

    If so, that sounds completely fair to me that it would be slower. Go and (try to) install Vista on a machine that originally came with XP (pre-SP1) and see how much slower it is. Is that a fair test either? I think not.

    As software gets more useful (and Ubuntu has, Vista not so much) it gets bigger and thus gets slower on the same hardware. Hardware advances at the same time though, so in real terms they keep about equal. When you test new software on old hardware of course it's going to be slower though.

      Indeed, it is common knowledge amoungst Real Programmers that you can run an arbitrarily large number of instructions per clock, allowing you to introduce entirely new functionality with zero performance hit. You just need to write everything in asssembler and have the right enchanted oils to annoint the heat sinks. By such a scheme CowboyNeal famously calculated the highest possible prime and now lives forever in a magic castle full of unicorns which shit rainbows.

      That's hardly a given, lots of software gets better as it ages - new features are added, but also performance tweaks get added.

      The problem is that software should be getting quicker on the same hardware, the alternative is bloaty apps that no-one wants to use. See Vista for the ultimate conclusion to that. You don;t want Ubuntu to end up the same, so its good that someone is pointing out performance issues. Hopefully the next release will have a few of these issues looked at and improved.

      You make it sound like it is inevitable and acceptable that newer software is slower than older software. I disagree. For one thing, one way to improve software is to make it faster. This is actually done sometimes. Secondly, even if you add features to software (which is another way to improve software), that doesn't have to make the software slower. In some cases, this may be inevitable, but in many cases it is not.

      I personally see computers, and software, as tools for making life more efficient. When software becomes slower, efficiency is actually lost. When this isn't offset by providing me with a more efficient work flow, I lose efficiency. Since efficiency is the main reason I use computers in the first place, this is a big deal.

    Complete bullshit article, doesn't offer any useful information beyond a completely obvious conclusion -- the more features that are added to a given piece of software, the higher the demands on your PC.

    I would think that those increased demands should be mostly in the form of slightly (a few MB) higher memory requirements to store the extra code for those features. Adding new functionality should not impact existing functionality. Haven't you heard of the zero-cost principle (idea from C++ and apparently Perl, "you don't pay for (as in take a performance hit from) what you don't use")?

    If you look closely you'll notice that (a) the benchmarks were run on a Thinkpad T60 laptop, and (b) there were significant differences on some benchmarks like RAM bandwidth that should have little or no OS components.

      Mod parent up.

      Many of the benchmarks (such as the lame, Java and RAM bandwidth benchmarks) are CPU-bound, and will run the majority of time in userspace. As the kernel should only be invoked for timer ticks, interrupts, TLB misses, etc (which would probably account for less than 1% of the CPU time), and change to the kernel should have minimal impact on the benchmarks.

      The parent's comment that power settings have been misconfigured sounds spot-on.

    Xubuntu's performance targeting appears limited to choice of desktop environment, which was a small component of what these benchmarks tested. The big performance increases the article talks about were in databases, compilers, encryption, memory access, and audio/video encoding/decoding, none of which really have much to do with the desktop environment.

  11. Performance Problems AREN'T Where You Think... by Anonymous Coward · · Score: 5, Interesting

    ... they are.

    Seriously.

    I can see several problems with the testing methodology as is:

        * The test suite itself: The Phoronix test suite runs on PHP. That in itself is a problem-- the slowdowns measured could most likely be *because* of differences in the distributed PHP runtimes. You can't just say "hey, version Y of distro X is slower than version Z! LOLZ" because, WTF. You're pretty much also running different versions of the *test suite* itself (since you have to consider the runtime as part of the test suite). Unless you remove that dependency, then sorry, you can't measure things reliably. Which brings me to my second point...

        * What exactly are they testing? The whole distro? The compiler (since most of the whole of each distro version is compiled with different versions of GCC)? The kernel? If they're testing the released kernel, then they should run static binaries that *test* the above, comparing kernel differences. If they're testing the compiler, then they should build the *same* compiled code on each version and run said compiled code (which is pretty much what I gather they're doing). If they're testing the utilities and apps that came with the distro, then they should have shell scripts and other tools (which run on a single runtime, not depending on the runtime(s) that came with the distro version). Because if you don't, you have no fucking clue what you're testing.

    Honestly, I was unimpressed by the benchmarks. I happen to do performance benchmarking as part of my job, and I can tell you, you have to eliminate all the variables first -- isolate things to be able to say "X is slow". If you rely on a PHP runtime, use *exactly* the same PHP runtime for all your testing; otherwise, you'll get misleading results.

    Take a look at some of the tests.
    "Computational: The Dhrystone 2 performance within the BYTE Unix Benchmark was also the fastest on Ubuntu 7.04. There was approximately a 20% drop in performance between 7.04 and 7.10 that remained consistent even in the 8.04 and 8.10 releases. "
    This is NOT in mono.
    "Database: In our SQLite test of measuring the time to perform 2,500 SQL inserts, the performance hadn't dropped off after Ubuntu 7.04 but instead after 8.04 LTS. In this performance drop it was over 2.5x slower. "
    SQLlite isn't written in mono.
    "but in our compilation benchmarks we spotted major performance losses following the Feisty Fawn release. It was noticeably slower to compile Apache, PHP, and ImageMagick in the 7.10, 8.04, and 8.10 releases."
    GCC isn't written in mono.

    Mod the parent up, I'm in the exact same boat. Ran Gentoo for three years, loved it, but realized that I was spending a lot more time tinkering with the OS than actually USING the OS. That's perfectly fine for a server of some variety where really the tinkering IS the interaction, but for a desktop or something you're going to use more interactively on a daily basis it became too much of a pain.

    Ubuntu gives me some of the strengths I liked (such as a simple, straightforward package manager, wide amount of customization without too much screwing around) without too many of the weaknesses (compiling all software, praying emerging the world doesn't break my desktop, so on and so forth).

    It's not a bad distro at all and it's tiring to hear of people slamming it for not being Slackware or Gentoo. This may come as a revelation, but Linux is about choice.
