Early Speed Tests For Windows 8 242

adeelarshad82 writes "You often hear in the software industry that performance optimization is one of the last steps in the software development process. That bodes well for Windows 8, considering at the early stage of Developer Preview—even before we've seen an actual beta—the nascent operating system is getting widespread praise for its performance, particularly in startup times. Anecdotal evidence is always encouraging, but PCMag decided to run some very early tests on the OS to see if the reports were wishful thinking or if there was a real, measurable boost in speed. Along with startup and shutdown times, they used several standard industry benchmarks to compare Windows 8 performance with that of Windows 7 running on the same machine."

    There are actually two kind of performances, which are both important. The real, actual performance, and how well the OS can make the system feel even under load. It's important to have a snappy feel even if the system underneath is working hard, and this is especially true now that the amount of cores in CPUs and multithreading are increasing. Say what you want, but just the feel of speediness is an important factor. This is why the boot up time is looked at so much too - it's great to quickly get to the desktop, and let the OS load up while you're already started working.

    One thing I've noticed with boot up times (and this applies to all operating systems) is that the OS tries to load all programs at once. Usually the limiting factor to this will be hard drive. It's less true with SSD drives, but it's really noticeable with 7200 RPM and slower drives. It usually leads to the whole system crawling for a few minutes after desktop shows up. It would be great if the OS would measure the different loads and UI response times, and actually limit the startup programs. This way you could open your browser and other tools and those would be given priority upon startup process.

    I tested the developer preview version briefly and it sure seemed a lot faster and snappier. The startup time is remarkably faster. And according to this PCMag test, seems like the overall speed has been improved a lot too. Good job MS!

      MS tried to throttle the startup programs in Vista so they don't all hit the disk at once, but reportedly gave up that idea in Windows 7:

      IMHO the time to desktop means nothing, especially on Windows as you note, the system isn't usable for minutes after the desktop's shown up. Adding in a faster drive (eg, an SSD or a hybrid drive) will cut down on the startup time, but the issue remains. So whether you load everything before showing the desktop or after will only make a difference in perceived bootup time, not in actual "time until the system is actually usable". In other words, it's just a cheap way to appear to boot faster without any actual benefit to the user.

        This, ten times over. When I swapped from XP to 7, first thing I noticed how fast it went from pressing the power button to seeing the desktop. Second was to notice that said desktop was completely useless for several minutes after becoming visible, and about 30 seconds after all applications have started. 7's caching is utterly retarded in this regard.

        XP was slower to boot to desktop, much faster to get desktop functional and applications started, and most importantly it was HONEST about it. It didn't pret

          What happened between 7 an XP was Intel giving MicroSoft a kick by donating a bunch of code to Linux that massively improved the boot times leaving MS to suddenly be far behind in that department.

          It's not he first time I've seen Intel do this and Microsoft reacts the same way every time and suspect that's Intel's new way of dealing with MicroSoft: Anytime they want MS to do something they give the code to Linux that does what they want in Linux.

        When you are forced to wait a few minutes before a computer is really ready to be used from the time you turn it on, then yes, the time it takes IS important. Those who get to the desktop but are still forced to wait before doing anything due to the machine still loading tons of garbage want to see an improvement there. I know that between the HP software for my printer and anti-virus, those take a bit of extra time before they are finished loading before my system is properly responsive, and THAT is wh

      The problem there is that with Linux, you can do a custom install that does not install anything you don't want to be running. Anti-virus on Linux? Nope, and many other things under Linux are also tuned to not start until you actually try to run them. With Debian, yes, you can get to a command line very very quickly, but once you fire up X11(whichever flavor you want), that adds a fair bit to the load time. If you set up for the system to come up with the GUI, your OS load time WILL increase.

      Startup time, until login screen, or desktop, or usable system, or fully usable system ....?

      The four are different and most people assume you mean the last, when most are measured to the first .... ...and unless you have a laptop why are you turning the machine on and off enough to worry about boot times (in the real world the difference between 20s and 1 minutes is a vast gulf, the difference between 1 minute and 5 minutes is irrelevant)

      • About year ago, I tuned my linux box (cheap single-core Intel Atom board, 5400rpm HDD, 1GB RAM) to boot into X in 8s (measured between hitting ENTER key and displaying search results for "asdf" on google in Opera browser). Video: http://www.youtube.com/watch?v=zE_QRZwNGOs [youtube.com]

        • So.. you mean it was in suspend and woke up tongue X screen in 8 seconds? My laptop does that faster. Unless you meant it was completely powered down, nothing store in RAM, etc and you pushed the power on button (which may double as an enter key, I have no clue)

      • Even with a laptop, I mostly use hibernate. Amount of time to come out of hibernate, even on Windows 7 is only about 20 seconds after BIOS. And that gives you fully usable system, with all the programs you had open previously. Reboot time is absolutely worthless, because I almost never reboot anymore. Once every couple of weeks for updates.

    Then you talk to a Microsoft turfer, as seen on here and other places, they will bald-faced lie to you and say "well, it's not finished yet, who knows what it will be like?"

    Then you go to the Microsoft fora and ask Microsoft employees about Metro as being standard for the upcoming desktop, they double-down on it.

    You often hear in the software industry that performance optimization is one of the last steps in the software development process.

    No you don't, not among sane people. You don't do performance optimization as "one of the last steps" shortly before shipping.

    What you hear is that "premature optimization is the root of all evil" (quoting Donald Knuth). What he meant is that you should not bother with complicated performance optimizations when designing the code. Rather, create and implement a good clean design, then test performance and optimize where needed. On the other hand, algorithm choice is one of the biggest performance contributors and initial choices will often be made quite early, so one cannot apply this quote blindly. Read here: http://en.wikipedia.org/wiki/Program_optimization [wikipedia.org]

      I suspect that the misunderstanding comes from the fact that Microsoft releases checked builds initially, with lots of debugging code some compiler optimizations disabled. So the perception is that they don't "optimize" the code until the final release.

    Ideally, a modern desktop OS should be booted once. The rest of the time it should be slipping in and out of sleep.

    In practice it seems that a few months between reboots (for OS updates) is easily attainable on some platforms.
    When a reboot occurs once every few months, boot time is not terribly important.

    I can't help but think that people who marvel at improved boot times are rebooting their machines too much.

    • I can't help but think that people who marvel at improved boot times are rebooting their machines too much.

    • Ideally, a modern desktop OS should be booted once. The rest of the time it should be slipping in and out of sleep.

      I know anecdotal evidence is frowned upon here, but my laptop with 4GB of ram and a 5400rpm disk takes about the same time to wake from hibernation as to boot*. Pair that with KDE's ability to restore sessions after a shutdown**, there is almost no advantage in putting it to sleep. I do suspend frequently, but that's more of a short-term solution with battery being used and lights blinking. And I can't sleep next to a running computer, I like silence in my room.

        Why? Do the math...

        a) How many megabytes per second can your hard drive read?
        b) How much RAM have you got?
        c) Divide (b) by (a)

        With 4Gb it's not really shocking that it takes quite a while to come back from hibernation. 8Gb probably takes longer than booting on most hard drives.

    • And in the UK its not cheap so yes, I shut my desktop down when I'm not using it and fully switch off the monitor. Aside from that it has an enviromental benefit downstream at the power station. Sleep mode might not use much power but it still uses some and with all the computers in the world that probably adds up to a lot of CO2 for nothing.

        I will admit that there are ways that system resources can be consumed and leaked, but in general it is hard for a user mode process to leak anything past process termination. Microsoft took that lesson to heart starting back in Win 95, and the system is very aggressive about keeping track of what process allocated what, and cleaning it all up when the process terminates.
