Be sure to download and read th actual 40 page report.
MS compares WindowsXP sp2 to GNU/Linux and FreeBSD, and in many tests, Windows loses.
Example of one instance...
Number of CPU cycles required to start and run a new process..
Linux: 719,000 FreeBSD: 1,032,000 WindowsXP SP2 5,376,000
When i have some free time and i finish the report, ill post back with some more comparasons.

QUOTE Linux: 719,000 Don't you think it's "linux in ascii terminal mode" and not "x-windows or KDE Linux"? Pure Linux should be compared to old ms-dos mode, and maybe ms-dos would win...

Naah don't think so - even with linux in console competing against ms-dos, it would win hands down... rather when it comes to linux/freebsd in console, there's no comparison at all.. ms-dos gets blown away to nothingness..

Hm, seems like it could be an interesting read. I'll have to look through it when I have a bit more time as I'm kinda busy right now. Awesome that MS was the one to do the study and release the results tho

By the way, I'm also surprised to see MS publishing this kind of results. I would expect this info to be "strictly for internal use" in the "for future improvement" department.

You dont seem to understand what is being said. The Linux kernel can start a new processor thread in that many cpu cycles. No matter wether you are loading the echo command, or HalfLife-2, a process thread is a process thread is a process thread as far as the kernel is concerned. Half-Life2 process will take no longer to start than a simple echo command in terms of cpu cycles. you are confusing process starting, with program and resource loading

QUOTE you are confusing process starting, with program and resource loading So, if it's the time for forking a process, it's normal that a full multi-task system like Linux does the job faster than Windows, which is not really multi-task nor multi-thread. Nevertheless, I would say that the real time is the time seen from the user part : time for starting the main process, malloc the needed memory, loading initial data and giving first user prompt. So, real time for loading a program and giving a result (echo "hello world" or calculating the 50th decimal value of pi for instance) would be the real way of testing several Operating systems. The old way of calculating the number of Mips or MegaFlops for each hardware for each OS was a good approach some years ago.

Its got nothing to do with forking. Its got nothing to do with Multi-users. And windows IS a multi-tasking OS. QUOTE I would say that the real time is the time seen from the user part and the time seen by the user is CPU cycles required divided by CPU speed. cpu cycles required is a very good measurement, because it is not effected by CPU load, nor other things that would interere with a clock method of timing. again you misunderstand. with a 3Ghz cpu, 700,000 cpu cycles is only a tiny tiny fraction of a secong... As is 5 million cycles. this is not a performance benchmark. just an indication of kernel sophistication.

Well, this is definitely not surprising. Windows already shows the problem when the user is using the operating system from the start. xboxrulz

I think by the time singularity comes out, Linux 3.0 would be out. Linux is taking forever to just jump major versions, it's been 10 years, but development is going 1,500 km/s... xboxrulz

I'm glad you people pointed that out, because reading the first page of posts it was bugging me that people seemed to think the whole article was M$ bashing themselves But yes, I would say this study is more reliable then the studies their marketing department uses, since it doesn't make windows look like ambrosia and it's not some random company doing the study as M$ pours dollars in their bank account to ensure 'correct' results :| Whether you like windows or microsoft or not, they aren't stupid. They know how to make themselves look better then they are, but its not like they all believe that... they just pretend to  But the singularity project seems pretty interesting, I didn't read the whole article but read a hadnful of sections that seemed interesting and it's cool that they are putting effort into this.

QUOTE What is the virtue of publishing this report, from Microsoft's view? QUOTE Read the whole document, as the original poster suggests, and think over. I think alot of people have comented without reading the article. the article is intented to show that the technology "singularity" will beat all current OS in certain area's. (some ideas sound really good) but in the porcess, they also show linux being able to do some things much ore efficiantly, for example, start new porcess threads. but hey... we never know what linux 3.0 will hold  The actual content of the study compareing current windows with current linux is a little trivial... its like compareing apples and pears and finding some apples are usually more round, and pears are usually less shiny. abut the reason i posted this link, was that it seemed to contradict the GET THE FACTS campain, which shows windows beeing twice as efficiant as linux in web serving.

What is the virtue of publishing this report, from Microsoft's view? It would have been much more interesting to analyze that point than to be blinded by the fact that, in some benchmarks, Windows scores less. Read the whole document, as the original poster suggests, and think over.

well, it's a matter of choice right. For instance, I like everyone to share my code, but I don't like people taking my code and then make money off it. Maybe you like it, but I surely don't  xboxrulz

How Linux Is Being Subverted
(0) Linux is in great danger at the moment. That danger started when Microsoft cut their deal with
Novell. Many open source advocates recognized this and there was a hue and cry over it. This furor
has died down to a large extent and apathy has set in. To combat this the Free Software Foundation
brought out their GPLv3 but this seems to be too little too late.
