WinTel 2.1 runs Windows on Intel Macs; developer promises up to 600 percent performance gains

“OpenOSX released WinTel 2.1, a new version of its software for running Windows on Intel Macs. The company claims performance gains of 300-to-600 percent over version 2.0 for Intel Macs. WinTel 2.1 now uses the QEMU virtual machine,” MacWindows reports.

“Last week we reported that open source developer Gwenolé Beauchesne had ported the open-source QEMU x86 virtual machine from PowerPC to Mac-Intel. OpenOSX is now using Beauchesne’s port of QEMU in WinTel 2.1,” MacWindows reports. “OpenOSX claims that WinTel 2.1 can boot Windows XP in just over half a minute on the 2.0 GHz iMac Intel with the 512-MB of RAM installed. WinTel 2.1 is a “universal” Mac application that can also run on PowerPC G4 and G5 Macs.”

  1. “Sounds as if Windows might be faster on a Mac than on a Winbox. Funny!”

    Macaday, it would be funny, if it were true. Unfortunately, the 600% performance improvement is compared to running under emulation on PowerPC based Macs, which could be described as slow as molasses going uphill in January, unless you had a very fast machine, in which case it would simply be described as slow as molasses.

    I wouldn’t count on Windows running faster inside of Mac OS X than natively on a similarly equipped PC. We should be happy if it runs just as fast. My guess is we’ll see a slight (5-10%) loss in performance from Mac OS X’s and the virtual machine software overhead.

  2. AndyC —

    OpenOSX has a history of re-packaging open source projects. Technically they’re allowed to do this, even with the GPL, as long as they claim it’s a “distribution fee” and as long as any code they create either interfaces with the GPL’d code only in certain ways or is also released under the GPL.

    What they do is not illegal, but a lot of it is simple to do on your own if you’re willing to do a little leg work. They also do a lot of re-branding so that people who don’t know better think the whole project came from OpenOSX — also not illegal, and there’s a time-hallowed legal tradition of including the important information in tiny type.

  3. ‘Sounds like’ not ‘IS’ ie the half a minute quoted to load Win XP is quick in my experience with that guck..

    I think it’s funny but otherwise I’m not in the slightest bit interested. This may bring more companies over to OSX knowing a legacy app or two needn’t be lost to them…

  4. Frank Rizzo? The dead former mayor and police commissioner of Philadelphia, who reveled in having his ‘boys in blue’ take nightsticks to the heads of brown-skinned people throughout the 60s & 70s, is software coding? From the grave?

    How interesting …
