Talk, Rumors, X Versus Y Linux Foundation Executive Director Jim Zemlin has said it is time for Solaris to simply move out of the way and yield the future to Linux. 'The future is Linux and Microsoft Windows. It is not Unix or Solaris,' he claims, contending that Sun's strength in long-lifecycle apps is giving way to Linux, as evidenced by the rise of Web apps, where Linux holds a decided advantage, Zemlin claims. With capabilities such as ZFS and DTrace, Sun is trying to compete based on minor features, he says. 'That's literally like noticing the view from a third-story building as it burns to the ground.'

Mostly I agree with you. I think SUN tried to protect their cash cow SPARC cpu. But nowadays an ordinary x86 is way faster for single threaded work. And way cheaper. The T2 SPARC shines with multi threaded apps, such as webserver. An T2 SPARC does work ~95% of the time under full load, whereas an x86 server CPU does work 40-50% under full load. So an T2 waits for data 5% of the time whereas an x86 waits for data 50-60%. Under full load.

Say an x86 CPU is running at 3GHz. As it can only work at 50% of it's capacity because of cache misses, it is something like 1.5GHz. That is not much faster than T2 at 1.4 GHz. Pity though the T2 threads are weak.

But the new SPARC Rock CPU will maybe change that again. It is SUN's highend CPU and it is supposed to have transactional memory! (Not fully developed transactional memory, it is too hard to do). It seems the ROCK will rock the house seriously:

"Sun Microsystems is about to horsef--k the database world, and nobody sees it coming. Imagine a SQL database that can support the absurd level of concurrency promised by HyTM. Conveniently, Sun owns one of the most popular relational databases in the world: MySQL. If MySQL on a single Rock based system can outperform Oracle or Microsoft spread across many systems, then DBAs worldwide would gladly tell Larry Ellison or Steve Ballmer where to shove it."
