Sun Solaris, OpenSolaris "Oracle today announced Oracle Solaris 11.1, delivering over 300 new performance and feature enhancements to the Oracle Solaris 11 product family." This stuff goes way over my head.

Let's stop talking about "stability", "scalability" and "performance" in vague terms. That's what the salespeople do.

In 2012, what do we mean exactly by "performance", "stability" and "scalability". In what way is it better or worse than, say, Linux or Windows?

Performance - let's start grounding it - do we mean disk performance? Do we mean network throughput? Latency? Do we mean performance of the core maths libraries?

Scalability - again - do we mean ability to scale with larger memory? Concurrent threads or apps hitting the network io? Memory manager and task scheduler coping with growing number of processes? Threads?

Stability - this is a funny one. I've never seen a good definition when people enthuse about their favourite OS' stability. Do they mean uptime left on its own? Do they mean not losing data when hit by a web-request storm? Do they mean ability to keep lots of processes happy and not kill them when memory is starved?

Do they mean that the level of bugs is low - so things don't crash or restart or just not work? Maybe we should measure "correctness" of an OS instead here?

The last time I say any attempt to quantify and compare such things was about 10 years ago http://bulk.fefe.de/ --- we don't see reviews of OS releases like that anymore.

I can't believe 80% of Linux reviews are reviews of how pretty the installer is, the desktop theme and the default package selection.

That drives me nuts as well! Those are the least significant parts of a running system.

But sadly, the most important ones considered by possible users. The "first sight effect" is important here. So any OS, no matter how powerful it is, will not appeal if the installer isn't a pretty conglomerate of GUI dialogs, in sequential manner, with defaults tailored for desktop use. Even among "geeks" (those who actually install an OS, because ordinary users aren't aware of what it is) this seems to be more and more important, and mostly found in... Linux reviews, yes.

Is there really anything else that distinguishes one Linux "distro" from another?
