NILFS2: A Slow But Dependable Linux File-System

Last week when benchmarking the new F2FS file-system from Samsung that was introduced in the Linux 3.8 kernel its performance was compared to Btrfs, EXT3, EXT4, XFS, JFS, and ReiserFS. For those hoping to see file-system performance results of NILFS2, those results are available today.

F2FS File-System Runs Great On SDHC Storage

Earlier this week I performed some F2FS file-system benchmarks on the Linux 3.8 kernel with an Intel X25 Solid-State Drive (SSD) compared to the EXT4, Btrfs, and other file-systems. Out today are benchmarks of the Flash-Friendly File-System from an SDHC card on Linux.

F2FS File-System Shows Hope, Runs Against Btrfs & EXT4

Being released soon is the Linux 3.8 kernel and one of its many new features is the introduction of the F2FS file-system. The "Flash-Friendly File-System" was developed by Samsung and is showing promise as a new Linux file-system designed around the characteristics of flash-based storage devices. In this article are the first benchmarks of F2FS compared to Btrfs, EXT3, EXT4, XFS, JFS, and ReiserFS file-systems.

Benchmarking The New Optimization Level In GCC 4.8

GCC 4.8 is set to introduce a new optimization level that provides fast compilation performance and decent run-time performance of the resulting binary while still providing a superior debugging experience. Here are benchmarks of this new GCC general optimization level (-Og) compared to the other long-standing compiler optimization levels.

PathScale EKOPath 5.0 Beta Compiler Performance

Going on two years ago PathScale open-sourced their EKOPath 4 Compiler Suite. This Fortran/C/C++ compiler suite hasn't seen widespread adoption since then outside of some scientific circles and other select high-performance areas, but PathScale hasn't stalled in advancing their compiler software that is also still available commercially. PathScale has been preparing to release EKOPath 5.0, which is the subject of today's benchmarks.
