Mac OS X: Solaris Inside 2

Posted by Bill McGonigle Thu, 07 Jun 2007 20:55:00 GMT

WWDC prediction - hey, all the kids are doing it.

Solaris, Open Solaris.

Under Mac OS X. Briefly:

  • xnu/mach is really slow. Linux blows away OSX when threads are concerned. Solaris doesn’t have this problem
  • ZFS: Sun already announced that OSX will default to ZFS as its filesystem.
    • This is a Solaris technology.
    • Tested code is essential.
    • Steve Jobs doesn’t let anybody else give away the biggies. Just ZFS is therefore a minor part of the announcement.
  • DTrace: Looking on the ADC site, there are WWDC sessions on DTrace, another Solaris techonology
  • Nexenta is Ubuntu on OpenSolaris - proof that you can skin a kernel
  • OpenSolaris to go GPL3. Jonathan Schwartz has said as much, assuming he likes the final license
  • Here is a picture from the WWDC lobby. A Sun is behind OSX. Game, set, match.

    Yeah, except Schwartz appears to have pissed someone at Apple off as some of the Sun oriented sessions at WWDC have suddenly been taken off the agenda...

    Hey, you must've seen something I missed on there. I still see DTrace listed here:
