GCC 4.9 Compiler Benchmarks On A Dual-Core Haswell

While extensive benchmarks of the GCC 4.9 development compiler are currently ongoing, here's a preview of the performance that the GNU Compiler Collection is set to offer in 2014 with its next major update. For this article an Intel Pentium "Haswell" dual-core processor was tested on a GCC 4.9 development snapshot and compared to GCC 4.8.2 and GCC 4.7.3 in a wide variety of C/C++ workloads. New LLVM Clang 3.4 benchmarks are also happening.

Oibaf Keeps Making Ubuntu GPU Driver Upgrades Easy

For those that may have some time this holiday weekend and are looking to better enhance the performance of Ubuntu's open-source graphics drivers, one of the easiest ways to do so is by enabling the Oibaf repository for easily downloading and installing newer versions of the Mesa/Gallium3D drivers and other X.Org related components. Here are some more details and current benchmarks of enabling the Oibaf PPA over Ubuntu 13.10.

Linux 3.0, 3.4, 3.10, 3.12 AMD Kernel Benchmarks

How does the Linux kernel performance compare if simply bouncing between some of the recent long-term kernel releases? Well, to try to answer that question on Phoronix today we have benchmarks of the Linux 3.0.101, 3.4.68, 3.10.18, and 3.12.0 kernel releases tested from an AMD Opteron system with Radeon graphics.

XMir Performance Measured On Ubuntu 13.10

While the Ubuntu 13.10 desktop isn't using Mir/XMir by default, the packages are available within the archive for those wanting to test out the next-generation display server for Ubuntu. To see how the 2D/3D performance is when running under XMir with the Unity System Compositor, I ran some new benchmarks using this week's Ubuntu 13.10 release.

Liquorix 3.11 Kernel Benchmarks

It's been several kernel releases since last benchmarking the Liquorix kernel, an optimized version of the Linux kernel that's advertised as "built using the best configuration and kernel sources for desktop, multimedia, and gaming workloads." In Liquorix having out their version of the Linux 3.11 kernel since late September, here are some benchmarks comparing Liquorix to recent mainline versions of the vanilla Linux kernel.
