Microsoft Claims OpenDocument is Too Slow

SirClicksalot writes "Microsoft claims that the OpenDocument Format (ODF) is too slow for easy use. They cite a study carried out by ZDNet.com that compared OpenOffice.org 2.0 with the XML formats in Microsoft Office 2003. This comes after the international standards body ISO approved ODF earlier this month." From the ZDNet article: "'The use of OpenDocument documents is slower to the point of not really being satisfactory,' Alan Yates, the general manager of Microsoft's information worker strategy, told ZDNet UK on Wednesday. 'The Open XML format is designed for performance. XML is fundamentally slower than binary formats so we have made sure that customers won't notice a big difference in performance.'"

      I've noticed that Word will stream open a large DOC file, so that you can start to work on it before it's been entirely loaded -- similar to a web page.

      DOC files don't so much as stream as open for Random Access. They're structured in such a way that the information is stored as an object heirarchy scattered across the file. This makes saving faster because only the changes are saved to the file. It also make opening faster, because Office only needs to pull up the information that's on the screen at the moment. (Even if it's at the end of the document.) PDFs work in a similar, but more structured, fashion.

      The unfortunate fact about ODF is that it requires a complete decoding of the file when loading, and a complete reencoding of the file when saving. However, I don't see any reason why Microsoft can't just add ODF support and make it an optional format. Computers are fast these days, and it should be up to the user to decide whether he needs the performance provided by the MS DOC *cough* "standard".

      End result: OpenOffice 2.0 opens ODT about twice as fast as it opens Word .DOC files (it took about 1 second to open the doc and about 0.5 seconds to open the ODT).

      It is not surprising that OpenOffice opens its preferred (well-documented) format faster than it opens someone else's non-documented format.

      The inverse test (opening both DOC and ODT in Word) is not possible for obvious reasons! However opening the .DOC in Word was even faster (0.3 seconds? ... hard to measure).

      Conclusion: Word opening DOC is probably faster than OO2.0 opening ODT. However the difference is so small that no one should care (on modern hardware especially). Furthermore there's no reason not to believe that opening of ODT documents will get faster and smoother as time goes on, since the standard is published and algorithms for opening ODT can be improved openly with time. Not only that, but since OO2.0 is open-source, it's particular implementation can be improved.

      both methods use the same compression methods and are of the same type and data types.. one gives you better compression but is and is faster to extract but is horid at random openings and updates where as a normal archive doesn't have the horid side affects but doesn't give you the higher compression or the speed in extracting.

MS XML is not going to be so easy - inline binary and lookup tables for content.

In the long run, there is no competition - the maintainable code wins hands down for anything that has evolving customer needs (which, except for those that have been cancelled, is every project I have seen).

It makes the code harder to write, understand, and maintain, and it solves a problem that doesn't happen in normal operating conditions. If there's a problem with software or hardware failures during write, do what OOo and MSO already do - keep a backup while the file is open. Once the file is on disk, it is very unlikely to be truncated or bit-flipped unless the drive goes bad (in which case you are going to have a hard time recovering it anyway). If you need your data to withstand drive failures, use an off-disk, off-site, or off-line repository as appropriate.

  15. MS App Tweaks by Gallenod · · Score: 5, Interesting

    This brings to mind something that Microsoft did in the mid 1990's. When MS Word was trying to wrest market share from Wordperfect, Microsoft apparently coded speed bumps into Windows that only their programmers knew how to avoid. Microsoft then claimed that MS applications were "better" becuase they were faster, though we didn't understand that it was because of intentional handicapping of their rivals' software until they'd pretty much crushed WordPerfect in the market.

    It kind of makes me wonder if they'll try the same approach to make ODF look "slower," by optimizing MS apps to work with Open XML and fumble around with ODF files.

    Actually the problem is not binary versus none binary, its fixed length versus variable length fields and records.
    With old style formats, you knew that the header was 512bytes followed by 600 bytes of meta data, followed by the document sections which all indicate their size (or have some way of calculating it based upon the block type)

    With XML, you get a tag opening and have to parse until the closure, this adds a lot to the complexity of reading.

    Writing is slightly different, and should infact be simpler with XML even though it may be more verbose, you don't need to buffer the entire block or rewrite the section header to indicate the length, you just happily do a sequential write.

  17. Oh Right... by Greyfox · · Score: 5, Insightful
    Like performance has ever been a cocnern of Microsoft's. If that were the case, window frames would be handled outside the application so that you could still operate on the window if the application freezes up. If that were the case, Outlook would gather mail in a separate thread so that when the exchange server stops responding I'd still be able to read and compose local email. Or minimize its fucking window. If that were the case, no application could sieze control of eveything else going on at the moment to tell me it's done searching and that I should now click OK.

    In fact, until this very day I didn't even realize that performance was even in Microsoft's dictionary, and like so many other words Microsoft uses I don't think it means entirely what they think it means. Newsflash, Microsoft, "innovation" does not mean "steal other people's ideas." "Security" does not mean "It'll be taken over before you can download the first update for it." And "performance" doesn't mean "the entire fucking system stops for 30 seconds when some application decides to stop handling its windows controls." Now STFU and go back to pushing your poison kool-aid on unsuspecting consumers before Apple eats your lunch.

    ODT XML files are binary files. So are old Word 2003 .doc files. So are Microsoft's new XML files. So it's pointless to claim that a "binary" file format is faster than an XML file format.
    When people say "binary files" they mean this as opposed to "text files", a seperation that stems from the ability to open a file for in "binary" or "textfile" modus in several APIs. Has to do with, amongst others, interpretation of control codes such as ^Z.

    The other big mistake: file formats aren't fast or slow. The algorithms for reading and writing them are (or aren't) slow.
    *slaps cheek* NO WAI!

    You fail to see the point of what they're saying. They're saying a binary file, with a header and fixed data structures, are alot easier to read & parse than an XML file, which consists of structures of variable length, needs to be interpreted, etc etc etc. This is a problem with XML.

    There is something true in that study, indeed.
    Personally I already have seen this kind of numbers, even though I've never minded to measure them.
    Why? Simply put, because it matters very little.
    Compared to Windows 3.11, Windows XP needs 100 times more disk space, 10 times more RAM and 10 times more time to boot.
    Compared MS to Word 5.5, MS Word 2003 if slower and bigger.
    Today I wouldn't revert back to Windows 3.11 and would not choose Word 5.5. What'd be the most important features expected in a document file format? In my opinion:
    1. compactness
    2. openness
    3. flexibility
    No "access performances", though.
    Because the time needed to load a document, when you do real office work, weighs by far less than the time you spend on it while working.
    And when someone sends you a file written with a different version of the software or even with a different software, how much time do you spend to make that file readable and printable?

  22. Reminds me of 'performance speak' from psych paper by The+OPTiCIAN · · Score: 4, Informative

    This reminded me of this paper, "The Psychology of Learning". In it the writer describes the act of people who don't want to learn new things: "As long as everybody around them use tools, techniques, and methods that they themselves know, they can count on outperforming these other people. But when the people around them start learning different, perhaps better, ways, they must defend themselves. Other people having other knowledge might require learning to keep up with performance, and learning, as we pointed out, increases the risk of failure. One possibility for these people is to discredit other people's knowledge. If done well, it would eliminate the need for the extra effort to learn, which would fit very well with their objectives."

    This issue is about Microsoft defending their turf rather than not wanting to learn something new. But it's basically the same motive at work: find ways to undermine the new to benefit the old.

    It goes on, "This model of learning also explains other surprising behavior that I frequently observe. I have seen novices in software development with knowledge of a single programming language explain to experienced expert developers why their choice of programming language was a particularly bad one. In one case, I talked to a student of computer science who told me why a particular programming language was bad. In fact he told me it was so bad that he had moved to a different university in order to avoid courses that used that particular language. When asked, he admitted he had never written a single program in that language. He simply did not know what he was talking about. And he was willing to fight for it. With respect to programming languages, negative opinions about a language that a person does not know, are usually based on very superficial aspects of it. To people obsessed with performance lack of such in a programming language is a favorite reason to advocate its eradication (even though performance is not a quality of a language, but of a particular implementation)."

    The positive lesson to take away from this is the MS is undoing itself. It's turning to cheap, nasty, suit-driven mentalities to defend its turf rather than the old days when it would just go out and write something new and nasty. It's become an unwieldy beast. I read about the Vista delays yesterday and briefly thought "Will anyone notice - who uses Windows these days". To an extent it shows what a bubble I live in. But it's true - *all* of my regular contacts use linux, freebsd or mac os x. As they should. After all - friends don't let friends use Windows.

    OpenOffice uses ODF. Office uses binary formats. The performance analysis quoted doesn't compare ODF and OpenXML. It states right in the article:

    Here is a comparison with the standard 16-sheet SXC and XML sample file I've been using. The sample is in compressed XML format because it is smaller and easier for you to download. You'll have to convert the XML file to XLS and the SXC file to ODS to run the following test yourself.

    XLS is a binary format. This study is irrelevant to the statements made. And it's the only data given to substantiate the claims made. So there is no data given at all.

    All you can conclude from this is that OpenOffice 2.0, retrofitted recently for ODF, is much slower in a windows environment than Office 2003 using binary file formats. A far cry from any statements made either by Yates or by the summary.
