Due to there being much interest in the ARM Cortex A15 benchmarks on Linux, namely with the Samsung Chromebook and its Samsung Exynos 5 Dual, here's a weekend special providing some GCC compiler benchmarks of this new ARM chip.

In this article are benchmarks of the latest Linux 3.7 kernel development code of the EXT4, XFS, and Btrfs file-systems.

Following last month's Btrfs file-system tuning benchmarks, in this article are a similar set of tests when stressing the EXT4 file-system with its various performance-related mount options. Here are a number of EXT4 benchmarks from Ubuntu 12.10 with different mount option configurations.

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.

The latest ARM Linux benchmarks to share at Phoronix is a comparison of Ubuntu 12.10, Linaro 12.10, Fedora 17, and Arch Linux when running from the dual-core Cortex-A9 OMAP4460-based PandaBoard ES development board.

With LLVM/Clang 3.2 being released next month and the code branching occurring this month, here's some new benchmarks from the latest SVN development snapshot as of this weekend. LLVM/Clang 3.2 SVN benchmarks were compared to the earlier LLVM 3.1 and 3.0 releases for reference.

This month from CPUs based upon AMD's new Piledriver micro-architecture I have delivered results of compiler tuning on AMD's Open64 compiler as well as GCC bdver2 tuning. That initial testing from an AMD FX-8350 Eight-Core processor didn't show any big boost out of the "bdver2" target with the new BMI/TBM/F16C/FMA3 instruction set extensions. Testing in this article from the AMD FX-8350 are GCC compiler benchmarks of the 4.6.3, 4.7.2, and 4.8.0 development snapshots to look for performance improvements on this new high-end AMD processor when using the very latest GCC compiler code.

With this week's unveiling of the FX-8350 eight-core processor being based on AMD's new Piledriver architecture, in this article are benchmarks when testing out the Piledriver "bdver2" optimizations within AMD's own Open64 compiler.

As some more benchmarks from the Calxeda EnergyCore ECX-100 ARM Server -- a.k.a. the "5-Watt Linux Server" -- to share this weekend, here is a ARMv7 Cortex-A9 GCC compiler performance comparison.

Earlier this week I posted new Reiser4 file-system benchmarks that compared the non-mainline file-system against EXT4, Btrfs, XFS, and ReiserFS. Continuing in the Linux file-system performance theme, in this article are more Btrfs benchmarks from that same system but when using the early Linux 3.7 development kernel and trying out different Btrfs mount/tuning options.
