GCC 4.6/4.7/4.8 ARMv7 Compiler Benchmarks

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.

Btrfs File-System Tuning On Linux 3.7

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.

AMD Piledriver/Trinity A10-5800K Compiler Tuning

With the initial Linux results for the AMD A10-5800K Trinity APU now out of the way along with the Radeon HD 7660D graphics performance, in this article are some benchmarks looking at the impact of compiler tuning for the Piledriver cores using the common GCC compiler and testing different CPU micro-architecture targets.

Reiser4 Benchmarked On Linux 3.5

While the Reiser4 file-system has been in-development for the better part of the past decade, it still hasn't been merged into the mainline Linux kernel. Reiser4 is still out-of-tree, doesn't see much new development activity by its limited developers, and the file-system remains tarnished due to its founder, Hans Reiser, being a convicted murderer. However, Edward Shishkin the former Namesys employee, does continue to drive its development forward. Reiser4 was recently updated to work with the more modern Linux 3.5 kernel.

LLVM/Clang 3.2 SVN Compiler Performance

With LLVM 3.2 set for release in mid-December, the time to benchmark this next major compiler infrastructure release paired with the Clang C/C++ compiler is approaching. Well, that time has already come; up this weekend are some benchmarks of the Intel Core i7 3960X "Sandy Bridge Extreme Edition" on Ubuntu 12.04 when comparing LLVM/Clang 3.1 to their latest SVN development code for LLVM/Clang 3.2 as of this week.

X11 Turns 25 Years Old Today

It was 25 years ago today, on 15 September 1987, that Version 11 Release 1 of the X Window System (a.k.a. X11) was released. X11 has evolved a long way since then, but this 25-year-old technology out of MIT remains at the heart of every Linux desktop.

Why Mono Is Desirable For Linux

On this Friday we have a freelance open-source opinion article that was written by Ciprian Khlud. This developer, who uses C# among other languages at his place of employment along with a combination of Windows and Linux, argues why the Mono open-source ECMA CLI/C#/.NET implementation is actually desirable for Linux.
