OS X Snow Leopard to Use ULE Scheduler?

Ever since Steve Jobs first unveiled the next version of OS X, dubbed “Snow Leopard,” the internet has been abuzz with excitement and wondering about the supposed “evolutionary” qualities of OS X 10.6. One of the most-hyped improvements is the promised revamp of the SMP capabilities of OS X, with a “breakthrough” in SMP performance.

The codename for the technology behind the SMP improvements in OS X Snow Leopard has been named “Grand Central,” which Apple describes best:

“Grand Central,” a new set of technologies built into Snow Leopard, brings unrivaled support for multicore systems to Mac OS X. More cores, not faster clock speeds, drive performance increases in today’s processors. Grand Central takes full advantage by making all of Mac OS X multicore aware and optimizing it for allocating tasks across multiple cores and processors. Grand Central also makes it much easier for developers to create programs that squeeze every last drop of power from multicore systems.

Our guess is that these SMP “breakthroughs” are going to be delivered in two blows:

  1. Improvements to the OS X kernel intended to boost multi-threading & multi-tasking performance and better-distribute the loads across multiple CPU cores more intelligently.
  2. Provide an SDK (perhaps as improvements to XCode) that allows developers to more-easily write multi-threaded code, handle forking, and provide load-balancing features on a per-core basis.

Firefox 3 is Still a Memory Hog

One of the biggest “improvements” that Mozilla claims has made its way into Firefox 3 is improved memory usage, in particular, the vanquishing of memory leaks:

Memory usage: Several new technologies work together to reduce the amount of memory used by Firefox 3 over a web browsing session. Memory cycles are broken and collected by an automated cycle collector, a new memory allocator reduces fragmentation, hundreds of leaks have been fixed, and caching strategies have been tuned.

We’re sorry to have to break it to you, but if you thought it was too good to be true you were right. Firefox still uses a lot of memory – way too much memory for a web browser.

Shipping Seven is a Fraud.

A blog titled Shipping Seven has gotten a lot of traffic recently for their article about Windows 7 and the MinWin kernel – namely, how they’re actually one and the same. The argument offered by “Soma” is that Windows Vista’s kernel (which is what Windows 7 will be built on) is MinWin ad that it’s already on every Vista desktop out there.

Whether or not MinWin is the very same kernel that went into Vista or not is officially unknown at the moment; but what we do know is that Shipping Seven is either one huge fake, or else that the Windows core programmers at Microsoft are so stupid that they don’t know the first thing about coding, kernels, operating systems and compilers.

The post at Shipping Seven is littered from beginning to end with fallacies, lies, and incorrect deductions that anyone with even the most basic coding skills would know better than to ever post, especially not when attempting to pass it off as the work of some of the more talented coders out there.
