Composition bypass support finally landed this morning into the mainline Mir code-base ahead of the Ubuntu 13.10 feature-freeze. With the feature being merged and packages already being pushed into the 13.10 archive, benchmarks at Phoronix have already been conducted. The benchmarks to share this afternoon are of the Mir/XMir packages from yesterday against the Mir packages today with composite bypass support. Lastly, there are benchmarks of a pure X.Org Server running on the same hardware to look at the performance impact and current (reduced) overhead of Mir.

With the recent release of ZFS On Linux 0.6.2 that provides an open-source native Linux kernel module implementation of the Sun/Oracle ZFS file-system, the performance is faster, there are greater Linux kernel compatibility, and other improvements. Here's a fresh round of ZFS Linux benchmarks against EXT4 and Btrfs.

On the latest Linux 3.10 stable kernel we have taken ten common Linux file-systems and generated an interesting performance comparisons. The Linux file-systems being tested in this article include XFS, Btrfs, EXT2, EXT3, EXT4, ReiserFS, Reiser4, JFS, F2FS, and ZFS.

With quite some time having passed since we last benchmarked the Reiser4 file-system, to end out July we have some fresh benchmarks of Reiser4 from the newly released patches for the Linux 3.10 kernel. There's fairly good performance out of the experimental file-system when compared to the original ReiserFS as well as EXT4, Btrfs, and XFS.

To complement the LLVM 3.4 SVN compiler benchmarks from yesterday that were looking at the impact of using the SLP Vectorizer that's soon to be enabled by default for some optimization levels, here are some more LLVM Clang compiler development benchmarks. This time around are fresh benchmarks of the open-source C/C++ compiler when trying out the different compiler optimization levels, including -O0, -O1, -O2, -Os, -O3, and -Ofast.

To complement the EXT4, XFS, Btrfs, and F2FS benchmark results that were published yesterday from the Linux 3.11 kernel and its predecessors, here are some Btrfs tuning benchmarks on the Linux 3.11 kernel with various performance-sensitive Btrfs mount options being tried.

Coming out today are our first Linux 3.11 kernel file-system benchmarks. Being benchmarked from a higher-end OCZ Vertex 3 SATA 3.0 SSD connected to an Intel Core i7 "Haswell" system are the EXT4, Btrfs, XFS, and F2FS file-systems.

Along with benchmarking the AMD A10-6800K "Richland" APU on Linux and its Radeon HD 8670D graphics, I provided some GCC compiler tuning benchmarks for this AMD APU with Piledriver cores. The latest Linux testing from the A10-6800K is a comparison of GCC 4.8.1 to LLVM/Clang 3.3 on this latest-generation AMD low-power system.

On Friday I delivered the first benchmarks of Ubuntu's Unity desktop running on XMir -- the X.Org Server compatibility layer for talking to the Mir Display Server. Those benchmarks showered there was noticeable performance overhead to running XMir with Intel's graphics driver. Later benchmarks showed XMir 2D performance was also negatively affected. In this article are benchmarks looking at the XMir performance with the Nouveau driver.
