XP SP2 Can Slow Down Business Apps 359

Posted by timothy from the tradeoffs-are-everywhere dept.
An anonymous reader submits "Mobile PC magazine installed XP SP2 on a bunch of notebooks and benchmarked them, finding that SP2 caused a 9-percent performance reduction in business productivity apps. While a couple of notebooks performed better, the majority took a 3- to 22-percent performance hit." For now, the story is just at the top of the Mobile PC website, but they promise more details in an upcoming issue.

    This is probably due to them recompiling a large number of libraries and system components with the buffer checking and other security features they added into the recent versions of Visual C++. If you ask me, it's worth it, just to know that my Windows box has a few less wide open holes to be exploited.

    It definitely has proven its worth so far - I may be wrong, but I'm pretty sure the reason SP2 isn't vulnerable to that GDI+ JPEG exploit is that they recompiled GDI+ with buffer checks.

      Correct me if I'm wrong, but shouldn't this have been done right in the beginning itself?

      If I were writing any commercial grade code, especially stuff that I know that people would take advantage of, I would sure as hell make sure that I had all my buffer checks in place.

      I've heard so much about the programming practices at Microsoft and what not - and yet, ironically, these things keep cropping up so damn bloody often while some operating systems [openbsd.org] coded by a bunch of loosely connected hackers are way more robust and stable.
      Hmm, makes one wonder.

      (Heh, funnily OpenBSD site says - Only one remote hole in the default install, in more than 8 years! - I guess it does say a lot).

      I do not understand, I would have thought that despite all the shit that MS gets for writing bad code, they would make sure that their code is largely buffer checked. Now, when you have to release stuff from outside to patch up for those, you would obviously be wasting a lot more cycles than if you had done so in the beginning, and well.

      Sheesh. They do not do a good job of making software and cause you inconvenience, then they release something to make up for it, and that causes you even more inconvenience.

        99 buffer checks don't do you any good if one buffer is missing a check, and that one gets exploited.

        That's what their compiler modifications are intended to help with, and from my experience, they help. I do agree that it should have been done sooner, though.

          The reason I brought that up was because I was interview by Microsoft last summer at Seattle, and one of the groups that interviewed me was the systems group.

          (Funnily, systems wasn't even my area, but still they interviewed me, but that's another story...)

          They were of the opinion that since MS is a favourite target of hackers and the like, any MS programmer ought to go to extraordinary lengths to patch any and all buffer checks and foo bar. I was asked to write some piece of code for compiler design and memory management, and the guy kept harping on buffer checks.

          I would imagine that with ALL those checks, such things would not be common - but lo! and behold, there they are.

          Either they are not doing a good job of doing the whole buffer check thing that the guy harped to me about and it was all hogwash to impress upon you how "important" and "hard" coding in MS is, or there is something seriously wrong with the codebase that SO many exploits turn out everyday.

              Uh hmm, your argument is flawed for the simple reason that just because Linux has buggy code, does not excuse Microsoft from writing good code.

              And comparing Dennis Ritchie's code with today's code is again flawed - hell, why, given my today's knowledge of Physics and Mathematics that I learn by my twelfth grade, I would have been the most intelligent man alive 400 years ago.

              You do not compare with what Dennis did or might have done, you make a reality check with how things are today - there is a fair section of crackers who want to exploit systems, and if you are in the business of writing commercial code, you'd better be darned good at making sure your code is good because customers are *paying* you for it.

              I have another issue with MS - they concentrate more on releasing things early than checking the code full before releasing. If this were an isolated issue, I would not have a problem - it is not. And MS has had so many years in the market, so many top-notch programmers AND the resources. If you want to compare, look at OpenBSD - that's an example of OpenSource code done right - with one remote exploit in 8 years.

              Linux is still in it's infancy, and for all that it's capable of it, it's quite unfair to compare it with the products of a 20 year old behemoth. If you ask me, Linux is doing a fantastic job of being a top notch enterprise systems in such a short time, when compared to Microsoft. And very few of the people behind it actually make any money of it. Does that not say a lot?

                  I was not trying to flame MS for their past actions - however Microsoft started out with a fairly clean codebase for both Win2k and WinXP. Given that, it seems bad that such vulnerabilities keep coming up.

                  I do agree that both Win2k and WinXP are a lot more stable than their predecessors. However, you would think that when you are doing something the second time, you would double-check to make sure that you do not make the same mistakes as you did the first time.

                  I just feel that this is not happening - and any number of factors could be contributing to it (market, economics, manpower, complexity what not) - but that does not mean you do not take the pains to not do it well. I'm sure Microsoft's trying to take as much care as they can to ensure that this does not happen.

                  However, despite that, these still seem to be happening. Which is what I find quite baffling - there seems to be a fundamental flaw somewhere in there, and that needs to be taken care of. Which is what I mentioned in my initial posting, too.

        specifically, the /GS flag to the VC++ compiler.

        The compiler was modified to support automatic stack overflow checking (i.e. canaries). Server 2003 was compiled with this (and as a result, MANY things that are shared-code problems resulting in exploits on other NT based OSes are either ineffective or DoS attacks on Server 2003).

        The idea is that /GS compiled binaries will cause the OS to terminate the app rather then letting code execute. The source code generally doesn't need changes.

        So, its a defense in depth tactic. Ideally, there'd be no BO's in code. But there are. Terminating the program with an explanation as to why is better than letting people run code on your box. :)

        • Ah! I wasn't aware of that.

          So would they be recompiling all their stuff that shows up an exploit with the new compiler, to ensure that BOs don't happen? :)

          Given the frequency of exploits that turn up, if MS kept releasing such patches ever so often, that would quite terribly slow down the whole system. On the other hand, like you rightly pointed out, better a slower running program that terminates by popping an explanation than an exploit.

          Oh well, the price of slavery ;)

    If you thought SP2 would be a speed upgrade then you also buy the previous lines that Win98, ME, NT4, W2K, XP would make Windows faster than previous versions. Of course these fallacies are based on the assumption that you would install the upgrade on a *newer* PC than their sample set. No Windows update has ever been faster than its predecessors.

    Period.

    If I post an "article" on my 5 megs of webspace provided to me by my ISP denouncing Windows XP saying that installing SP2 will steal my first born and rape my cats, then "create" some benchmarks to prove my point, then submit the article to slashdot, will it make it on the frontpage?

    I'll even conclude in the article that running linux will solve world hunger and even do my laundry.

    Correct me if I'm wrong, but given today's hardware, is 10-20% slowdown even noticeable to the average user running, say, Word? IIRC, the threshold for user to notice anything meaningful is around 30% in day-to-day operations.

    Games are a different beast, but does the user even care if loading a spreadsheet takes an extra second or two?

    9% on average on "Business Apps" is to vague too draw any conclusions. Was the slowdown in disk, network, memory, network performance? All of the above?

    The slowdown could mean that MS cut some corners and traded speed for security in XPs' pre SP2 version. While fixing security problems they had to perform some extra checks and that dragged performance down. Or, they could've discovered some serious architectural issues with fixing new holes, so they had to do it in a slow and inefficient way due to the fact that their architecture wasn't designed with those checks in mind.

    On a side note, I experienced a significant slowdown when running Norton AV that supposedly does a bunch of extra security checks. File and network performance became unbearable at times. It got so bad that I had to ditch NAV so now I am reverting my Windows system every day (I run it under VMWare, Linux is a host system). I found this setup + Zone Alarm to be a better answer to endless Windows security issues.

    Maybe Microsoft needs to determine what the most common software installed on Windows PCs is and even work with software manufactures directly to ensure the greatest compatibility.

    Note the /NoExecute=AlwaysOff option in the article.

    Well known cause for much of the slow down some people find with SP2. Of course, this opens you up to morphic/purposefully overwritten code exploits, but such is life.

    • Hmm.... from the KB article

      Currently, the only x86 processors that support No-Execute functionality are the AMD 32/64-bit Opteron and Athlon-64.

      Since this doesn't affect Intel, this can't account for all the slow-downs people are expieriencing.

    This should actually be posted in the politics corner. I gotta admit ./ is doing a lot better job at playing politics then certain US canidates. Seriously, a service pack to perform maintence and add some very usefull features. What is the general response? "SP2 broke my edonkey and made my girlfriend (online) break up with me." OH OH! now its slower with certain progams because they switched some compile flags that they should have enabled years ago!

    I've attempted to install SP2 on three machines now and I'm not trying any more. After the 1st install, the system blue screened, and could not be recovered, had to reinstall from scratch.

    The second attempted install got about 2/3rds of the way done and then crashed resulting in an unstable system. The partial install could not be completely removed, and the machine would crash often, another reinstall from scratch.

    the third attempted install died in the early stages repeatedly (about 15 seconds after starting the install) and never got past that point.

    These were three completely different systems with different software installed, but all ended up with the same result, no SP2 without a complete clean installation of XP first. I'm so disgusted with MSs QA right now, I never plan to install SP2 again, because my time is too valuable to spend entire days rebuilding systems just because they can't write updates to their software.

    Hell in Gentoo and Debian I update the entire system with a single command and download hundreds of software packages equalling hundreds of MBs and it all goes smooth as silk, can't MS figure out how to copy files from an update package into the system without blowing it all to hell?

    Unsecure software runs faster. All that extra checking things to make sure they're valid and so forth requires processing power. I mean, a login script that just accepts any password entered would require less processing than one that actually checks the data against some other data.

    After installing SP2, defragment your hard drive - so many core files are replaced that the system's performance will be even more sub-optimal than usual until you do this.

    Since installing SP2 on a laptop, the printouts from Treeview Pro (a directory listing program) have had every printed character flipped on its vertical axis - all the letters are in the right place but the wrong way round so - for example, all 'b's look like 'd' - it's readable but makes your brain hurt!!

    Does anyone have a weirder SP2 effect?
