Windows Is So Slow, but Why? - New York Times
Back in 1998, the federal government declared that its landmark antitrust suit against the Microsoft Corporation was not merely a matter of law enforcement, but a defense of innovation. The concern was that the company was wielding its market power and its strategy of bundling more and more features into its dominant Windows desktop operating system to thwart competition and stifle innovation.
Windows 95 had 15 million lines of code. That grew to 18 million lines by the time Windows 98 launched, above. Windows XP, released in 2001, has 35 million lines of code.
Eight years later, long after Microsoft lost and then settled the antitrust case, it turns out that Windows is indeed stifling innovation — at Microsoft.
The company’s marathon effort to come up with the a new version of its desktop operating system, called Windows Vista, has repeatedly stalled. Last week, in the latest setback, Microsoft conceded that Vista would not be ready for consumers until January, missing the holiday sales season, to the chagrin of personal computer makers and electronics retailers — and those computer users eager to move up from Windows XP, a five-year-old product.
In those five years, Apple Computer has turned out four new versions of its Macintosh operating system, beating Microsoft to market with features that will be in Vista, like desktop search, advanced 3-D graphics and “widgets,” an array of small, single-purpose programs like news tickers, traffic reports and weather maps.
So what’s wrong with Microsoft? There is, after all, no shortage of smart software engineers working at the corporate campus in Redmond, Wash. The problem, it seems, is largely that Microsoft’s past success and its bundling strategy have become a weakness.
Windows runs on 330 million personal computers worldwide. Three hundred PC manufacturers around the world install Windows on their machines; thousands of devices like printers, scanners and music players plug into Windows computers; and tens of thousands of third-party software applications run on Windows. And a crucial reason Microsoft holds more than 90 percent of the PC operating system market is that the company strains to make sure software and hardware that ran on previous versions of Windows will also work on the new one — compatibility, in computing terms.
As a result, each new version of Windows carries the baggage of its past. As Windows has grown, the technical challenge has become increasingly daunting. Several thousand engineers have labored to build and test Windows Vista, a sprawling, complex software construction project with 50 million lines of code, or more than 40 percent larger than Windows XP.
“Windows is now so big and onerous because of the size of its code base, the size of its ecosystem and its insistence on compatibility with the legacy hardware and software, that it just slows everything down,” observed David B. Yoffie, a professor at the Harvard Business School. “That’s why a company like Apple has such an easier time of innovation.”
Microsoft certainly understands the problem, the need to change and the potential long-term threat to its business from rivals like Apple, the free Linux operating system, and from companies like Google that distribute software as a service over the Internet.
In an internal memo last October, Ray Ozzie, chief technical officer, who joined Microsoft last year, wrote, “Complexity kills. It sucks the life out of developers, it makes products difficult to plan, build and test, it introduces security challenges and it causes end-user and administrator frustration.”
Last Monday afternoon, James Allchin, the longtime engineering executive who leads the Vista team, held a meeting with 75 Windows managers and senior engineers to discuss the status of Vista. On Tuesday morning, Mr. Allchin met with a handful of his lieutenants and told them of the decision to push back the consumer introduction, a move that was announced publicly later that day, after the close of the stock market.
Brad Goldberg, a general manager of Windows program management, who attended the Tuesday morning meeting, said he was not surprised, because he had been involved in the decision. “But it’s a different place than Microsoft a few years ago would have wound up,” he said.
Like other Microsoft executives, Mr. Goldberg bristles at the notion that little innovative work has come out of the Windows group since XP. In the last five years, he said, Microsoft has released two versions of the Windows Tablet PC software intended for pen-based notebook computers, and four versions of Windows Media Center. To combat viruses plaguing Windows, much of the engineering team focused for 18 months on fixing security flaws for a downloadable “service pack” in 2004.
