One of the nice changes to the kstat (kernel statistics) command in illumos is its conversion to C from perl. There were several areas in the illumos (nee OpenSolaris) code where perl had been used. But these were too few to maintain critical mass and it is difficult for interpreted runtimes to change at the pace of an OS, so keeping the two in lockstep is simply not worthwhile.
Latency and performance problems in storage subsystems can be tricky to understand and tune. If you've ever been stuck in a traffic jam or waited in line to get into a concert, you know that queues can be frustrating to understand and trying on your patience. In modern computing systems, there are many different queues and any time we must share a constrained resource, one or more queues will magically appear in the architecture.
As you know Oracle Solaris 11 (11.1, 11.2) comes with Firefox 17 ESR and Mozilla 17 ESR, which is very good news.

I've just pushed 2964 into illumos, which adds support for a bunch of new libc calls for thread safe and thread-specific locales, as well as explicit locale_t objects. Some of the interfaces added fall under the BSD/MacOS X "xlocale" class of functions.
Oracle VM 3.3 was announced today,
providing substantial enhancements to Oracle's server virtualization product family. I'll focus on a few enhancements to Oracle VM Manager support for SPARC that will appeal to SPARC users:
I started my blog June 17, 2004, tempted by the opportunity of Sun’s blogging policy, and cajoled by Bryan Cantrill’s presentation to the Solaris Kernel Team “Guerrilla Marketing” (net: Sun has forgotten about Solaris so let’s get the word out). I was a skeptical blogger.
