Solaris 11 outperforms RHEL 6 on 2 socket Intel servers [30731]
Compare SPECjbb on servers with same Intel chips
Along time Sun employee writes, "I've often heard the term "Slow-laris" applied to Oracle's premier Unix operating system. Most frequently this was in comparison to the Linux OS running on small two socket servers. I will admit that in the Solaris 8 and 9 timeframe engineering decisions were made to benefit scalability to 64 sockets that sometimes penalized smaller servers. In addition, because of Solaris long history and derivation from ATT and BSD Unix code, there was undoubtedly a bit of code labeled, "if it ain't broke, don't fix it."
With the advent of Solaris 10 and Dynamic Tracing, (DTrace) we actually hunted down and killed a number of those legacy code segments using a new philosophy labeled internally, "If Solaris is slower than Linux on the same hardware, it's a bug."
As a result, Solaris 11 provides higher performance than Red Hat Enterprise Linux 6.3 on basically identical 2 socket hardware as measured by the SPECjbb benchmark..."

How Oracle Solaris Engineering Thinks [30532]
Solaris Engineer Liane Praza Pulls Back the Curtain
In two brief videos (both about two minutes long) recorded at Oracle Solaris Innovations Workshop, Solaris Engineer Liane Praza explains why Oracle Solaris engineering continues to build virtualization capabilities into the OS instead of adding more features and better management to the hypervisor and then explains what it is about Solaris that makes it such a good platform for managing virtual machines . As Rick Ramsey notes, this is a perfect opportunity to glimpse how Oracle's engineering staff think about Solaris and the other solutions that emerge from their shop.

Oracle Solaris and SPARC Performance [30626]
Larry Wake draws attention to Steve Sistare's three-part blog
Larry Wake draws attention to Steve Sistare's three-part blog "Massive Solaris Scalability for the T5-8 and M5-32," in which he discusses scaling a general purpose operating system to handle a single system image with thousands of CPUs and tens of terabytes (TB) of memory; in Part 2 he explains how improvements to Solaris enable superior performance and scaling on T5 and M5 systems, and in part 3 he focuses on enhancements made in the Scheduler, Devices, Tools, and Reboot areas of Solaris.

Upgrade Paths to Solaris 11 for Solaris 10 Customers [30524]
Collection of Video Interviews with Solaris Engineering Team Members
There is a collection of six brief videos by various hands that consider Solaris innovations from the engineering point of view. Speakers include Bart Smaalders of Core Solaris Engineering on why engineering did not provide a direct upgrade path to Oracle Solaris 11; Markus Flierl of Solaris engineering on innovations in Solaris for Oracle database and middleware; Liane Praza of Solaris engineering on Manageability and Analytics throughout the "stack"; Don Kretsch of the Solaris Studio team on SPARC T5 optimizations; Larry Wake of Solaris Product Marketing on continued business value of SysAdmin skills; and Mike Palmeter of Solaris Product Management on OS relevance.

Solaris 10 1/13 Patchset Released and Latest Solaris 10 Kernel PatchIDs [30429]
Download Available for Solaris 10 1/13 as Alternative
Oracle has releases a patchset of all the patches contained in Solaris 10 1/13 (Update 11) for both SPARC and x86 systems. The patchset includes an important post-S10U11 patch - 150125-01 (SPARC) / 149637-02 (x86) - and a fix for ZFS Bug 15809921. According to Gerry Haskins' post, this patchset can be applied to any existing Solaris 10 system to bring all pre-existing packages up to the same software level as Solaris 10 1/13. As an alternative to using the patchset, users can instead download Solaris 10 1/12, which will additionally install any new packages delivered in the Update.
