What Linux Users Are Saying About GNOME In 2012 (Part 1)

With the 2012 GNOME User Survey now officially over, here's the start of the results. In this posting are the first (of two) batches of feedback that users supplied while filling out the survey. This year there were 4,494 people participating in the annual yet independent GNOME survey. Of the nearly 4.5k respondents, 1,950 of them also provided feedback with this first batch consisting of the first one thousand responses. The results from the survey in full will also be published this week.

There's Another Linux Kernel Power Problem

After last year discovering a major Linux kernel power regression that was widely debated until the Phoronix test automation software bisected the problem to get to the bottom of the situation, there's more active power regressions today on the Linux desktop. As I've mentioned on Twitter and in other articles in weeks prior there's a few regressions, but one of them for at least some notebooks is causing a very significant increase in power consumption. This situation that remains unresolved as of the Linux 3.7 kernel can cause the system to be going through about 20% more power.

LLVM/Clang vs. GCC On The ARM Cortex-A15 Preview

The latest ARM Cortex-A15 benchmarks on Phoronix is an extension of the earlier compiler testing from this modern ARM CPU found on the Samsung Exynos 5 Dual within the Samsung Chromebook. In this round of performance testing, the LLVM/Clang compiler performance is compared to recent releases of the GNU Compiler Collection on this latest-generation ARM hardware.

Benchmarking LLVM/Clang 3.2, GCC 4.8, DragonEgg Compilers

Earlier this week I shared some updated benchmarks of the latest development code for LLVM/Clang 3.2 on an Intel Core i7 processor. Now from this same setup to complement the LLVM 3.1/3.2 benchmarks are results of the GCC 4.7.2 compiler, the latest GCC 4.8 development snapshot, and benchmarks of GCC when using LLVM's DragonEgg 3.1/3.2-SVN optimizer plug-in.
